The name of this caramel-like confection, from Argentina and Uruguay, loosely translates to "milk candy": In a traditional process, sugar and milk are cooked over low heat for hours, until the mixture becomes thick and golden. Make your own dulce de leche, or find it in the international aisle or a Latin-foods market. It's great spread on toast, drizzled over tropical fruit such as mango, used as a dip for apple slices, or whipped into butter and spread on cornbread.
