4 large egg whites
1 cup white sugar
pinch of salt
1 teaspoon vanilla extract
Put egg whites, sugar and salt in a glass or metal bowl over a simmering pot of water. Whisk constantly until sugar dissolves and mixture is hot to the touch. Add vanilla.
Pour mixture into large bowl or mixer bowl and beat for 3 minutes until fluffy. I used the whisk attachment to do this.
For this picture I put the icing in a sandwich bag, snipped the end and piped it on to make swirly tops.
This is great on cupcakes or as icing for a cake. Filling for cupcakes. Eating with a spoon. You could possibly make rice krispie treats with it.
