The delicious "Arequipe"

Here is a recipe for Arequipe, or Dulce de Leche:

3 quarts milk
2 lbs. sugarpinch of salt
1/4 t. baking soda
2 egg yolks
cinnamon stick

Combine ingredients in a saucepan and simmer until thickened. Stir constantly, preferably with a wooden spoon, until you see the saucepan while stirring (4-5 hours). Add the egg yolks and let cook 2 or 3 minutes longer. Remove cinnamon stick. Let cool. This recipe must be watched constantly.

There is also a shortcut for preparing Arequipe. Put a can of sweetened condensed milk in a pot of boiling water. The water should fully cover the can which must not be opened. Boil it for about 5 hours adding water constantly to compensate evaporation. Let it cool down for 30 min before opening the can and you'll get a pretty good Arequipe
