  2. Gradually add powdered sugar while beating until the icing is smooth, about 30 minutes.

Frost the cake

  1. If the cake is rough, dust with flour and remove loose particles with a cloth.

  2. Pour the frosting around the center of the cake and smooth it with a knife.

  3. If the frosting is stiff, dip the knife in cold water.

  4. Frost the cake while it is still warm.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg whites
Whipped into a stiff foam that gives the frosting its light, airy structure.
Powdered sugar
Dissolves into the foam to sweeten and thicken the frosting into a smooth icing.

The step that matters

Beating the egg whites to a stiff froth. Egg whites must be whipped until they hold stiff peaks, since the air trapped in the foam gives the frosting its lightness. Under-whipped whites will leave the icing runny and flat.
