Why it works: Sugar and banana are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 3,102 recipes. Both carry 1-penten-3-one, which smells fish, pungent. The science ↓

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):
- Vanillafits better
- Raisinfits better
- Lemonfits better
- 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.
