1/4 cup and 1 tablespoon cornstarch
Dash of salt
1/2 cup white sugar
3 cups skim milk
6 ounces semi-sweet baking chocolate or any good-quality chocolate chips
1  cup chocolate chips
1/2 teaspoon vanilla extract

Pour the milk into a heavy, medium-sized sauce pan. Whisk in the cornstarch, salt and sugar until there are no lumps. Place the saucepan on medium-low heat and cook for 8 to 10 minutes, stirring continuously. Make sure to scrape the bottom and sides of the pot. When the mixture has thickened, add in the chocolate. Stir continuously for another 2 to 3 minutes until the chocolate is completely melted in and the mixture is now a beautiful brown. Add in the vanilla, stir until mixed in. Place in the serving dishes and chill in the refrigerator until firmly set, around 2 to 3 hours.
