Potato Frittata Recipe, Spotlight on Condimento Bianco Senape and Blackcurrants, Steaming Potatoes, and A Surprising Benefit of Exercise for Women

Autumn is a wonderful time to get together with family and friends, and what better way than over brunch? If you’re looking for a simple yet satisfying dish, my potato frittata fits the bill. It features Condimento Bianco Senape, a unique vinegar in my brand new collection of artisanal vinegars from the T. J. Robinson Curated Culinary Selections. Sweet, fragrant, and with a hint of mustard, it’s crafted in the style of a fine Italian balsamic (read below to learn why there’s actually no such thing as “white balsamic”). You’ve never tasted anything like it before—get ready to fall in love! 

Also in this issue…I’m sharing fascinating research on blackcurrants, a powerful member of the berry family that might hold the answer to protecting women’s bones in midlife and beyond. Keep reading and you’ll also find out about a surprising benefit of exercise.

Potato Frittata

  • Potato Frittata Potato Frittata

    Elegant enough for a brunch party, this egg-and-potato dish is also easy enough for a casual weekend breakfast. The potatoes can be steamed a day or two in advance.

    Ingredients

    • 1 pound red potatoes
    • 8 eggs
    • 2 ounces freshly grated Parmigiano-Reggiano cheese
    • 2 tablespoons milk
    • 2 teaspoons freshly ground black pepper
    • Coarse sea salt
    • 3 tablespoons extra virgin olive oil, plus more for drizzling
    • 1 large leek, twiced rinsed, trimmed of the tough, dark green ends, and sliced into 1/4-inch discs
    • 2 tablespoons Condimento Bianco Senape, plus more for drizzling

    Directions

    Step 1

    Cut the potatoes into 1/4-inch slices. Steam them on a steamer rack over simmering water until tender, about 25 minutes. 

    Step 2

    In a bowl, whisk the eggs until no whites show, then whisk in the cheese, milk, black pepper, and 1 teaspoon salt until well combined. 

    Step 3

    Heat a 14-inch skillet over medium heat. When hot, add the olive oil and the leeks. Sprinkle with a big pinch of salt and sauté until the leeks soften and turn light brown, about 10 minutes. Layer on the potato slices, overlapping them a bit. Pour on the egg mixture. Cover the pan and cook without disturbing over medium heat until the eggs firm up, about 8 minutes. Drizzle on the vinegar, cover the pan again, and remove from heat. Let stand for 10 minutes before slicing into wedges. Drizzle each portion with more olive oil and vinegar.

Condimento Bianco Senape 

Condimento Bianco Senape, or White Condiment with Mustard

I want to set the record straight—“white balsamic” is not a recognized type of vinegar in Italy. That’s because, by its very nature, balsamic vinegar must be made solely with grape must (grape juice made from all parts of the grapes) that naturally darkens to its signature purple-brown color. That being said, my new Condimento Bianco Senape, or White Condiment with Mustard, is reminiscent of a fine balsamic because it’s crafted in the perfect ratio of two parts white cooked grape must to one part white wine vinegar by the amazing vinegar producers known for their balsamic vinegars, Società Agricola Acetomodena in Modena, Italy. Both the grape must and wine vinegar are made solely from Acemodena’s own Trebbiano grapes, which give it its unique light color, and not their Lambrusco ones, which give traditional balsamic its deep color. 

The idea for creating a complex, mustard-seed infused white wine vinegar in the sweet style of balsamic came from Patrizia Vecchi, the wife of Acetomodena owner Paolo Vecchi. She was inspired by the ancient Roman cooking technique of using a white vinegar along with honey and mustard to get a delicious crust on spit-roasted pork. The white mustard seeds, which are entirely edible, add a subtle layer of flavor to my Condimento Bianco Senape that would be lost in a traditional balsamic. 

You’ll use this mustard vinegar to effortlessly create a rich and silky vinaigrette just by whisking in fresh-pressed olive oil and a bit of salt and pepper. I love its sweetness yet will also blend it with other vinegars when I want a bit more tartness. Use it as a marinade for poultry, pork, and fish. Drizzle it on steak and burgers, gourmet sandwiches with prosciutto and other meats, bruschetta with tomatoes, fresh salads like rocket with pine nuts and a drizzle of honey, and my eggless Caesar salad which along with the potato frittata are just two of the many recipes included in the Vinegar Report that comes with the collection.

Steaming Potatoes

Steaming potatoes keeps them from falling apart and preserves more of their nutrients than boiling. Simply scrub and slice or cube your potatoes and arrange them in a steamer basket set over two inches of simmering water in a stockpot. You can load the basket with two layers of potatoes, but try to keep some space between the pieces for the steam to get through. The potatoes are done when the tip of a knife easily pierces the flesh; start checking after 25 minutes.

For Your Best Health: Blackcurrants for Better Bones?

Blackcurrants for Better Bones?

Research done at the University of Connecticut (UConn) has identified blackcurrants, a tart berry known in French foods and liqueurs as cassis, as a potential way of countering the bone density loss experienced by women in the years surrounding menopause. 

For many years, Ock Chun, PhD, MPH, professor of nutritional sciences in UConn’s College of Agriculture, Health and Natural Resources (CAHNR), has been investigating the berry’s potential to ameliorate a host of conditions including postmenopausal bone loss and osteoporosis. One of her previous studies showed that in mice, blackcurrant supplements helped prevent bone density loss postmenopause, and that the best time to start taking these supplements is in the transition between pre- and postmenopause, before bone loss has significantly progressed. With these findings in hand, Chun and her team wanted to see whether the benefits would translate to people. The new study, published in the Journal of Nutritional Biochemistry, found that the supplements prevented the loss of, and in some cases even increased, whole-body bone mineral density in women.

Blackcurrants

The study involved 40 perimenopausal and early postmenopausal participants between the ages of 45 and 60. They were randomly assigned to take either one or two capsules of blackcurrant powder (392 milligrams per capsule) or a placebo daily for six months. The researchers found that the supplements prevented the loss of whole-body bone mineral density and that the group of participants who took two capsules a day actually showed overall increases in bone mineral density at the end of the six-month trial period.

The researchers looked at changes to the gut microbiome and immune system, which interact to play a key role in bone metabolism. They found that the blackcurrant supplements decreased levels of proteins called interleukin-1 beta and RANKL. Interleukin-1 beta stimulates the expression of RANKL, which causes bone resorption and thus a decrease in bone density. “The reduction in RANKL is important because that can cause shifts toward excessive bone resorption, so we’d want to see a decrease in that,” said graduate student Briana Nosal, first author of the paper.

Taking the supplements also increased Ruminococcus 2, bacteria found in the gut microbiome that help degrade polysaccharides and fibers. This is a key function that transforms the foods we eat into energy. This led the researchers to infer that it could be one of the bacteria driving the protective effects blackcurrant has on bones. “It’s all related, and there’s a lot of research showing the gut can regulate various systems in the body,” Nosal said.

The researchers identified a total of four proteins that had increased expression in the group of participants who took two daily supplement capsules. These could serve as potential biomarkers for the changes in bone density that they observed and potentially allow researchers or medical professionals to quickly and easily assess whether the blackcurrant supplementation is benefiting bone density.

This study is especially important for perimenopausal and early postmenopausal women who have or are at risk of developing osteoporosis. While medications for osteoporosis do exist, compliance is low due because of side effects. If a blackcurrant supplement can improve bone density without the same side effects, it could prove to be an effective alternative.

As the research team continues to study the relationship between blackcurrant and its benefits to the body, they’ll try to better understand why exactly they’re seeing these results and “how all our findings connect to each other,” Nosal said. “Conducting that multifaceted research will really paint the picture of how everything works, the different mechanisms, and what we can do for next steps.”

A surprising Benefit of Exercise for Women

Recent research led by Donald S. Wright, MD, MHS, of the Department of Emergency Medicine at Yale School of Medicine and published in the American Journal of Preventive Medicine found that sticking with an exercise program is linked to older women staying out of the hospital.

This retrospective study evaluated 718 older adults with a mean age of 69.5; three-quarters were women. The researchers compared the outcomes of those who participated in a structured, individualized exercise training program at a privately owned gym in their community for at least three months (411 participants) to the outcomes of those who did not. The structured program consisted of guided sessions of cardiovascular, strength, and flexibility training monitored by exercise physiologists. Participants completed a baseline physical assessment and quarterly reassessments of physical performance including measuring vital signs, strength (bicep curl or grip strength), mobility (as measured by the ability to easily go from sitting to standing), balancing on one leg, and aerobic capacity. These data were paired with regional hospital data and a national mortality database. Participants were followed for over two years. 

When the researchers compared outcomes of older adults who participated in the exercise program with outcomes of those who did not, they found that the risk for all-cause hospitalization was 46 percent lower among the women in the exercise program. Surprisingly, this benefit was not seen among the men. 

The researchers pointed out that the study doesn’t establish cause and effect between exercise and not needing healthcare, just a link, albeit a positive one for women. It’s also not known whether the people who dropped out of the structured exercise program exercised independently, potentially narrowing the observed differences between the groups. They also warned that participants may not be fully representative of the broader US population because they were all from one area of the country and had all been motivated to sign up for the gym program on their own.

As the nights get cooler, warm, nourishing meals become even more tempting palate-pleasers. My recipe for stuffed shells truly satisfies—it’s one of the new seasonal recipes in the latest edition of my online cookbook Savor the Season: Autumn 2024. Put together family style, it’s a great dish for large gatherings—everyone can dig in on their own. It’s also a very filling meatless option. You’ll read why that’s important in the diabetes-prevention research I’m sharing. Then, to get a motivation boost for healthier living, take a look at some top tips from a leading fitness expert to help you stay on track with your exercise goals.

Spinach-and-Cheese-Stuffed Shells

  • Spinach-and-Cheese-Stuffed Shells Spinach-and-Cheese-Stuffed Shells

    This dish doesn’t just taste great; its pretty presentation will wow family and guests alike. You can make my fresh tomato sauce up to three days in advance, or use 3 cups of your favorite high-quality store-bought sauce for faster prep.

    Ingredients

    For the tomato sauce:

    • 3 tablespoons extra virgin olive oil
    • 4 large garlic cloves, minced
    • 1 cup grated yellow or Vidalia onions
    • One 6-ounce can tomato paste
    • 1/2 cup red wine
    • One 28-ounce can whole tomatoes, preferably San Marzano
    • 1/2 teaspoon dried oregano
    • Pinch of sea salt, more to taste

    For the shells:

    • 1 pound jumbo pasta shells
    • 2 teaspoons sea salt
    • 1 pound mozzarella
    • 1 pound ricotta cheese
    • 2 cups freshly grated Parmigiano-Reggiano cheese, divided use
    • 1 cup cooked spinach, well chopped
    • 2 tablespoons extra virgin olive oil, plus more for baking 
    • 1 egg, beaten
    • 1/2 teaspoon dried oregano
    • 1/4 teaspoon freshly grated nutmeg
    • 1/4 teaspoon freshly ground black pepper

    Directions

    Step 1

    Make the sauce: Heat a large saucepan. When hot, add the olive oil, garlic, and onions, and sauté until soft but not browned. Push the vegetables to the outside of the pan and add the tomato paste in the center. Sauté the paste until it browns, to release its flavors. Deglaze the pan with the red wine, then add the tomatoes, oregano, and salt. Use a potato masher to gently crush the tomatoes. Simmer for 20 minutes (or more) while you prepare the shells. 

    Step 2

    Make the stuffed shells: Bring a large pot of water to a rapid boil and add the shells and the salt. Cook according to package directions for al dente (don’t overcook, as the shells will soften more in the oven). 

    Step 3

    While the shells are boiling, line a rimmed sheet pan with parchment paper and set aside. Preheat your oven to 375°F. Cut the mozzarella into small cubes. Place the cubes in a large bowl along with the ricotta, 1 cup grated Parmigiano-Reggiano, spinach, olive oil, egg, oregano, nutmeg, and black pepper; mix thoroughly. 

    Step 4

    Drain the shells, place them on the prepared sheet pan, and use a small spoon to stuff them with the spinach-cheese mixture. Lightly coat a large round or rectangular baking dish with olive oil and add three-quarters of the sauce; use an offset spatula to spread it out evenly. 

    Step 5

    Place the filled shells in the baking dish in a festive pattern, brush the tops of the shells lightly with olive oil, and cover with the rest of the Parmigiano-Reggiano. Bake for 30 minutes or until the cheese topping is thoroughly melted and slightly browned. Serve with the rest of the tomato sauce on the side.

Healthy Ingredient Spotlight: San Marzano Tomatoes

Healthy Ingredient Spotlight

San Marzano Tomatoes

San Marzano Tomatoes

These uniquely shaped Italian tomatoes have long been considered the ultimate in sweetness, but as we’ve seen with olive oil and balsamic vinegar, it’s important to know what’s real and what isn’t. True San Marzano tomatoes are grown in Sarnese-Nocerino, near still-active Mount Vesuvius in the Campania region of Italy. The volcanic soil is responsible for the tomato’s near-perfect balance of sweetness and acidity.  

In recent years, consumers in the US have sued companies whose labels imply that the cans contain San Marzano tomatoes when they don’t. This is not to say that other tomatoes aren’t tasty, but if you want the real thing, look for labels with two essential logos: the red-and-yellow DOP (denominazione d’origine protetta,ordesignation of protected origin) stamp from the EU and the colorful logo of the Agro Sarnese-Nocerino Consorzio, which is the local consortium that makes sure the tomatoes are grown according to its rules. Also, San Marzano tomatoes are always canned whole, peeled, and only in their own juice.

Grating Parmigiano-Reggiano

Grating Parmigiano-Reggiano

If you’re a regular Newsletter reader, you know that only Parmigiano-Reggiano is true “Parmesan” cheese and it will have the word imprinted with a dot pattern all around the rind. How you grate it for a recipe, like my stuffed shells, or for a garnish on, say, Caesar salad, is more nuanced. It depends in part on whether the cheese is to seamlessly meld into a sauce, for instance, or stand out in the form of generous shavings. A sturdy vegetable peeler is a great way to get thin, narrow shavings: Run it along the edge of the wedge. For wide shavings, run a cheese plane over the surface of your wedge. Need a small amount of finely grated cheese? Pull out your microplane grater and shave the cheese right over your dish. For a larger amount, try a box grater—its four sides offer many options (place it over a large sheet of parchment paper to catch the gratings). If you want a very large amount, look to your food processor. Most steel blades will turn cubes into shreds. For a near-powder that will melt easily, Cuisinart has a very fine cheese grating blade that works in seconds—just cut off the rind, cut the cheese into pieces that will fit in the machine’s feed tube, and process. 

For Your Best Health: Reducing Type 2 Diabetes Risk

Reducing Type 2 Diabetes Risk

We know about the risks for heart disease and some forms of cancer associated with eating too much red and processed meat. Now an analysis of studies that included nearly two million people across 20 countries has also linked these foods to a higher risk for developing type 2 diabetes, a chronic condition that has reached epidemic proportions in the US, according to the National Institutes of Health. (Earlier studies made the association but had varying results.) This research, published in The Lancet Diabetes and Endocrinology, also looked at whether there’s a link between poultry and diabetes.

The team of scientists, led by researchers at the University of Cambridge in the UK, found that eating 50 grams of processed meat a day—that’s about 2 slices of ham—was associated with a 15 percent higher risk of developing type 2 diabetes in the next 10 years. Eating 100 grams of unprocessed red meat a day—that’s roughly a 3-ounce steak—was associated with a 10 percent higher risk. Eating 100 grams of poultry a day was associated with an 8 percent higher risk, but when further analyses were done to test the findings under different scenarios, the association for poultry consumption became weaker, whereas the associations with type 2 diabetes for both processed meat and unprocessed meat persisted.

Professor Nita Forouhi of the Medical Research Council (MRC) Epidemiology Unit at the University of Cambridge, a senior author on the paper, said, “Our research provides the most comprehensive evidence to date of an association between eating processed meat and unprocessed red meat and a higher future risk of type 2 diabetes. It supports recommendations to limit the consumption of processed meat and unprocessed red meat to reduce type 2 diabetes cases in the population. While our findings provide more comprehensive evidence on the association between poultry consumption and type 2 diabetes than was previously available, the link remains uncertain and needs to be investigated further.”

The team used theglobal InterConnect project for their work. It’s an approach that allows researchers to analyze individual participant data from diverse studies, rather than being limited to published results. This enabled the authors to include as many as 31 studies in this analysis, 18 of which had unpublished findings on the link between meat consumption and type 2 diabetes. By including this previously unpublished study data, the authors considerably expanded the evidence base and reduced the potential for bias from the exclusion of existing research, they explained.

Said Professor Nick Wareham, director of the MRC Epidemiology Unit and a senior author on the paper, “InterConnect enables us to study the risk factors for obesity and type 2 diabetes across populations in many different countries and continents around the world, helping include populations that are underrepresented in traditional meta-analyses…Using harmonized data and unified analytic methods across nearly two million participants allowed us to provide more concrete evidence of the link between consumption of different types of meat and type 2 diabetes than was previously possible.”

A Motivation Reboot

ACE Fitness, the leading organization for fitness professionals, recently published an inspiring blog on staying motivated, written by fitness expert Len Kravitz, PhD, coordinator of exercise science at the University of New Mexico, and students in his Introduction to Exercise Science course. Here are some of the ideas, abbreviated for space, that can help keep you on track with health and fitness goals, important because, as Dr. Kravitz pointed out, 80 percent of adults don’t meet current guidelines for aerobic exercise or resistance exercise. “These tips help target a person’s self-efficacy to adopt an exercise program and avoid dropping out,” he wrote. “As you read through this list, identify those strategies that resonate with you and fit best with your lifestyle, then incorporate those that will make the biggest impact.”

Set realistic health and fitness goals. Make sure they match your abilities, health, and lifestyle. Also break down even short-term three-month goals into smaller, more achievable segments of two to three weeks.

Create a weekly schedule that includes blocks of time for exercise. This helps with consistency.

Diversify. Mix up activities within each type of exercise—cardio, strength training, and flexibility. 

Track your progress. Seeing your achievements in black and white helps keep you enthusiastic. 

Create or join a network of fitness friends. Exercise loves company! 

Give yourself rewards. Treat yourself to new exercise clothes or gear, flowers, or something special you’ve been eyeing. 

Aim for consistency over intensity. Slow and steady wins the race. 

Set reminders. Use your smartphone to ping you 15 minutes before your scheduled workouts.

Create a vision board. This is a real or virtual poster composed of photos, drawings, and quotes that inspire you. 

Go small if needed. Some people find it easier to work out in 10-minute sessions—build up to three a day and you’ll meet daily recommendation of 30 minutes.

Get guidance. Consider hiring a personal trainer to provide expertise, guidance, education, and motivation tailored to you. This could be the smartest money you’ll ever spend on yourself and pay big dividends.
