Sugar 2 eggs (for the whites only) Cream of tartar Salt Vanilla
Place all ingredients into a thick-bottomed saucepot, starting with the sugar, then add salt, cream of tartar and egg whites.
Finally, add the water. Tip: We don’t add the vanilla extract until the end.
Place this mixture over medium-low heat. Beat it constantly for about 5 to 7 minutes, or until sugar dissolves and stiff peaks form.
Fold in the vanilla extract. Ice your cake with this 7-minute frosting and you’re good to go.
