Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and fat, which give the cake a tender crumb.
- Egg whites
- Trap air when beaten, giving the cake its light, rising structure.
- Powdered white sugar
- Sweetens the batter and helps stabilize the beaten eggs.
- Sifted flour
- Provides the starch and protein that set the cake's structure as it bakes.
The step that matters
Beat the mixture for 10 to 15 minutes. Long beating whips air into the eggs, and that trapped air is what makes the cake rise. Under-beating leaves a dense cake, so the batter should be well aerated before the flour goes in.
Swap the nutmeg
How well each one fits the dish's main ingredients (egg, sugar, flour):
- Jalapenofits better
- Cinnamonfits about as well
- Nutmegthe original
- Capersfits less well
Fit is the average pairing score against egg, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
