How to Beat Egg Whites
Using a copper bowl such as the Egg Beating Bowls pictured below to beat or whip egg whites is the prefered method to avoid overbeating which can result in clumpy egg whites.
Start with room temperature egg whites using copper beating bowls. Copper provides ions that migrate into the egg whites causing it harder to over beat. Egg whites beaten in a copper bowl will be slightly yellowish and more stable than ones beaten in other bowls.
