Dulces de Leche

Add all the ingredients in a pot and put the heat on high; stir constantly. When the sugar dissolves and starts boiling, turn the heat down to low and keep stirring. It will change color gradually, and stir until it is brown and thick like a paste. Using heat-resistant gloves under your food handling gloves, knead the paste and add pecans if wanted, or just add them on top; form little balls and place them in cupcake cups, or just put everything in a pan and cut into squares. The paste will dry and hard as it gets cold, and if that happens to you, just add a little bit of water or, with wet hands, knead it until you get a paste again.
