Craving the sweetness of dulce de leche but don’t want to go to the trouble of making it yourself? A store-bought brand (La Serenísima is excellent) is the way to go—just be sure to get 100 percent pure milk-and-sugar dulce de leche and not a “sauce” made with any additional ingredients. This combination of warm topping, salty hazelnuts, and vanilla bean ice cream is divine.
