Simple Seven Minute Icing
|Cream of tartar||1⁄8 Teaspoon|
|Grains of salt||To Taste|
|Cold water||3 Tablespoon|
|Sugar||3⁄4 Cup (12 tbs)|
Put all ingredients, except vanilla, in top of double boiler, over boiling water.
(Upper pan should not touch surface of water.) Beat with rotary beater for 7 minutes, or with an electric beater for 4 minutes, or until icing is stiff enough to stand in peaks.
Remove from heat and add vanilla.
If any graininess appears, add a few drops of lemon juice and continue beating until smooth.
Spread on cake immediately.
Makes enough for sides and top of two 8-inch layers.
For a 3-layer cake, double the recipe.
