cup cocoa powder
Mix the cocoa powder and the water in a saucepan. Heat and stir to dissolve the cocoa. Add the sugar, and stir to dissolve. Boil for 3 minutes over medium heat. Be careful not to let it get too hot and boil over! Add the salt and the vanilla. Let cool. Pour into a clean glass jar, and store in the refrigerator. Keeps for several months, but trust me it will be gone before then. Yields two cups.
