Milk chocolate sherbet ice cream recipe

Remember ordering a "400" at the soda fountain? Well now you can have it frozen. Icy, almost a granita. You'll
love it.
Melt 2 oz. Baker's chocolate, and add 1 cup whole milk, and 1 3/4cups sugar, 2 tbsp vanilla extract, and 4 cups
water. Mix thoroughly and freeze in the freezer section of your refrigerator in a shallow rectangular cake pan,
stirring every 20 minutes with a fork until frozen.
