Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, and helps give the cake a tender crumb.
- Eggs
- Provide structure as they set, and add richness and moisture.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Sugar
- Sweetens the cake, adds moisture, and helps it brown and stay tender.
- 7-up
- Adds liquid and a light lemon-lime flavor, with carbonation that helps lift the batter.
The step that matters
Beating in the eggs one at a time. Adding each egg fully before the next lets the butter and sugar emulsify into a smooth batter, which traps air and gives an even, fine crumb. Adding them all at once can split the batter.

Fit is the average pairing score against butter, sugar, egg, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
