It's the jam: Dulce de leche

South Americans love dulce de leche. The silky smooth, caramel-colored milk jam is so popular in Argentina, the country’s culture secretary issued a proclamation declaring it a proprietary product much like champagne is in France. We called Josephine Caminos Orìa to learn what’s so special about this tasty spread. At her company La Dorita, Orìa makes dulce de leche in small batches. She shares instructions for how to make it at home in “Dulce de Leche: Recipes, Stories & Sweet Traditions.”
