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 icing its light, airy structure.
Powdered sugar
Dissolves into the whipped whites to sweeten them and make the icing smooth.
Bananas
Cover the icing as a fruity topping that adds moisture and banana flavor.

The step that matters

Beat the egg whites until stiff. Egg whites must be whipped to stiff peaks before the sugar is added. Under-whipped whites stay runny and the icing will not hold its shape or spread well. Adding sugar gradually helps the foam stay stable and smooth.

Swap the banana

How well each one fits the dish's main ingredients (egg, sugar):

  1. Vanillafits better
  2. Raisinfits better
  3. Lemonfits better
  4. Bananathe original

Fit is the average pairing score against egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
