Strawberry Frosting (Swiss Buttercream) Recipe

Directions

Fill a wide pot with at least 1 1/2 inches of water, with a thick ring of crumpled tinfoil placed on the bottom to act as a "booster seat" that will prevent the bowl from touching the bottom of the pot. Place over high heat until steaming-hot and adjust temperature to maintain a gentle simmer. Combine egg whites, sugar, salt, and cream of tartar in the bowl of a stand mixer.
