Extra virgin olive oil gives classic lemon curd all the silkiness of butter without the saturated fat. It’s delicious spooned over Greek yogurt and topped with berries—serve it in a champagne glass for an indulgent yet good-for-you dessert. You can also use it to make a lemon tart—fill a baked and cooled 8″ tart shell with the chilled curd, and top with dollops of whipped cream.
- 3 large or 5 small lemons
- 2 large eggs, plus 1 yolk
- 10 tablespoons sugar
- 2 tablespoons cornstarch
- ½ teaspoon vanilla paste
- Pinch of sea salt
- 2 tablespoons mild extra virgin olive oil
Rinse the lemons, dry them thoroughly, and then zest them with a microplane grater. You should have a generous tablespoon of zest. Juice the lemons. You should have a generous cup of juice. Some pulp is fine to include, but remove any seeds.
In a heavy-bottomed saucepan, use a silicone whisk to blend the eggs thoroughly, and then whisk in one ingredient at a time in this order: sugar, cornstarch, lemon juice and zest, vanilla, and salt—this will give you the silkiest results without needing to strain the mixture after cooking.
Place the pan over medium heat and continue to whisk as you bring the mixture to a very low boil. Cook for two minutes (this activates the cornstarch), lowering the heat if necessary to prevent a rapid boil. The curd should be thick enough to coat the whisk.
Off the heat, slowly whisk in the olive oil until it’s completely blended in. Pour the curd into a glass pitcher or jar and allow it to come to room temperature before covering and placing it in the fridge to thicken further.
Yields 1-¾ cups.
