Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yellow cake mix
- Provides the flour, sugar and starch that form the cake's structure.
- Bananas
- Add moisture and natural sweetness to the crumb.
- Egg whites
- Help the batter set and give the cake lift and structure.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Olive oil
- Adds fat that keeps the cake moist and tender.
The step that matters
Frost only after the cake has cooled. Warm cake releases steam and softens the frosting, so the frosting can melt, slide off or sink in. Cooling the cake fully lets the frosting set in a smooth, stable layer.
Swap the banana
How well each one fits the dish's main ingredients (egg, olive, vanilla):
- Blueberryfits better
- Cherryfits better
- Coconutfits better
- Bananathe original
Fit is the average pairing score against egg, olive, vanilla. Candidates are from the same food group and used in at least 100 recipes.
