Place the sugar and cocoa in a saucepan and blend the mixture. Add the water and stir until blended. Bring the mixture to a boil and stir constantly for two minutes. Add the milk slowly and heat thoroughly, but do not boil. Serve with whipped cream, if desired.
Please note*** If you want to make a dry mix: My Thrive Instant Milk Can states: 1 cup water + 2 tablespoons dry milk = 1 cup milk. It also says (to make it easy) 4 cups water + 2/3 to 1 cup dry milk = 4 cups milk. My recipe calls for 4 cups milk so I would add 1 cup dry milk to the recipe with a note to add 4 cups water when making this recipe with the 1 cup Instant Dry Milk.
