Seven Minute Icing - cooking recipe

Ingredients

2 egg whites
1/3 tsp. cream of tartar
3 Tbsp. cold water
1 1/2 c. sugar
1/3 tsp. salt

Preparation

Put ingredients in top of double boiler and beat with rotary beater for 7 minutes.
(I always beat mine for a few minutes before I put it over hot water.
I think it makes a smoother icing.)
