Have to try: been doing this for years! it's a Brazilian staple! cook a sealed can of condensed milk in a pot boiling water for 3 hours. continue to add boiling water to cover the can as the water will evaporate. let can cool COMPLETELY. then open carefully & wahlah... dulce de leite :)
Arequipe :(Colombian dessert food that is also known as dulce de luche. It is a rich, very sweet caramel-type sauce ) Recipe: 3 liters of milk 2 pounds of sugar 1 pinch of salt ½ teaspoon of baking soda 1 stick of cinnamon. Put all ingredients in a pan, preferably copper, and left to simmer, without turning, until preparation looks thick. Then, stir with a large wooden spoon, and when you begin to see the bottom of the pan, remove from heat to other container.
