Combine 2 egg whites and 1 cup white corn sirup in a large bowl and beat with rotary beater until mixture will stand in peaks. Start at low speed and work up to high speed if you have an electric beater. Add 1-2 teaspoonful vanilla and 1-2 teaspoonful almond extract. Spread on cake. If any is left over cover bowl and set it in refrigerator and it will keep for several days.
