Chocolate Slush - cooking recipe

Ingredients

1 cup water
1 cup skim milk
1/4 cup granulated sugar
3 tablespoons unsweetened cocoa (I use Hershey's)
2 teaspoons vanilla extract

Preparation

Put milk through cocoa in a medium saucepan, cook on medium heat, stirring constantly until the mixture comes to a slow boil and sugar is dissolved Lower heat and simmer about 2 minutes, stirring mixture a few times (watching for burn/ boil over), stir in vanilla- set aside to cool Pour cooled mixture into a freezer safe covered container and freeze.
Place frozen mixture in a blender, blend to a slush.
Freeze any leftover portion.
Note: I use my coffee grinder to get a finer grind of the sugar, not powdered, just a fine grind.
