Chocolate Buttermilk Glaze and Frosting

This is a chocolate lover's ultimate glaze/frosting! Bittersweet and a little tangy, just the way it should be. A bit time consuming but worth it!










Ingredients:
1 cup sugar
1 cup unsweetened cocoa
1 1/4 cups buttermilk
1 tsp vanilla

Method:
Combine sugar and cocoa in a heavy bottomed medium saucepan. Use a wire whisk to stir in just enough buttermilk to form a smooth paste. Stir in the remaining buttermilk. Cook over medium heat until the mixture simmers and begins to boil, stirring constantly with a wooden spoon, scraping the sides and bottom of the pan. Boil gently for 3 minutes (2 minutes if you half the recipe - but why would you want to do that?) stirring constantly to prevent burning. Remove from heat and stir in vanilla. Pour through a fine strainer. Allow to cool. Cover, placing plastic wrap directly on the surface to prevent a skin from forming. Chill for several hours or overnight. Frosting will thicken as it cools. (May be refridgerated for up to a week).
Note: Boiling time is important here.
