White Mountain Frosting

My mom used to make a frosting like this so often.  I can remember her with a spoon seeing if she had a long thread.  My dad loved this frosting and so do I.  I forgot about this and have not made it often.  It is great on a dark chocolate cake, on a layer cake with a filling, on cupcakes.

White Mountain Frosting


Ingredients

3 cups white sugar
1 cup water
1/4 tsp. cream of tartar
3 egg whites
1 pinch salt
1 tsp vanilla extract

Directions

Combine sugar, water and cream of tartar in a saucepan.  Cook until candy thermometer reaches 238 degrees F (115 degrees C) or until syrup spins a long thread when dripped from a spoon.

Beat egg whites until stiff.  Pour a thin, slow dream of the syrup into the egg whites, beating constantly until frosting stand in peaks.

Stir in salt and vanilla to taste.
