- 12 eggs, separated
- 1/2 teaspoon salt
- 1 pound butter, room temperature
- 3 pounds confectioners' sugar
- 1 teaspoon vanilla extract
- 1 teaspoon ground nutmeg
- 1 teaspoon ground cloves
- 1 teaspoon ground allspice
- Beat egg whites and salt until foamy in a large glass or metal mixing bowl until stiff peaks form. Lift your beater or whisk straight up: the egg whites should form a sharp peak that holds its shape.
- Beat the egg yolks to soft peaks in a separate bowl. Beat the butter and confectioners' sugar in a large bowl until light and fluffy. Add the egg yolks and vanilla to the butter mixture; mix. Stir in the nutmeg, cloves, allspice, and the egg whites; beat until well blended. Batter can be frozen or kept in refrigerator for several weeks.
- To make a Tom and Jerry, fill a cup of hot water with spiced rum or brandy, warm milk, hot cocoa, or eggnog and stir in 1 heaping tablespoon of batter.
