Old-Fashioned 7-Minute Frosting Recipe

Old-Fashioned 7-Minute Frosting Recipe
Seven-minute frosting is the stuff of legend, at least for those of us of a certain generation—the pillowy white cloud of frosting our grandmothers spread over and between layers of cake. Every bite was a shock of marshmallow sweetness, little more than sugar and air, with nothing but a whisper of vanilla for flavor.

Ingredients:

2 large egg whites unbeaten

1 ½ cups granulated sugar

⅓ cup cold water

¼ teaspoon cream of tartar or 1 teaspoon corn syrup

1 teaspoon vanilla extract.
