How to make the famous 7-minute frosting
There’s nothing like a homemade frosting to complement the flavor of your homemade cake! This fluffy, versatile seven-minute frosting adds something special to almost any cake.
There are a few important things to remember when making this frosting. First, be sure to measure the ingredients accurately, especially the corn syrup. Before you start beating the frosting mixture over the heat, check that the water for the double boiler is at a full boil. Finally, a tip to know when it’s done: the icing is cooked enough when it piles up in soft little peaks that hold their shape.
2 egg whites
1-1/2 cups sugar
Dash of salt
1/3 cup water
2 teaspoons light corn syrup
1 teaspoon vanilla
Before putting the mixture on the heat, combine the egg whites, sugar, salt, water, and corn syrup in top of a double boiler. Beat about 1 minute, or until thoroughly mixed.
Next, place the top of the double boiler over boiling water, and beat constantly with a rotary beater (or at high speed of electric mixer) for 7 minutes, or until frosting will stand in stiff peaks, stirring frosting up from bottom and sides of pan occasionally with a rubber scraper, spatula or spoon.
Remove from boiling water. For a very smooth and satiny frosting, pour at once into a large bowl for a final beating. Finally, add vanilla and beat 1 minute, or until thick it is enough to spread.
Note: The mixture may be tinted by gently stirring in one or more drops of food coloring.
