Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cake's crumb together.
- Sugar
- Sweetens the cake, tenderizes the crumb, and helps it brown.
- Butter
- Adds fat that makes the crumb tender and rich.
- Eggs
- Set during baking to give structure, and add moisture and richness.
- Sour milk
- Its acidity reacts with baking soda and adds moisture.
- Baking soda
- Reacts with the acid in sour milk to release gas and lift the cake.
The step that matters
Fold in the beaten egg whites.. Folding gently keeps the air beaten into the egg whites, which gives the cake lift. Stirring hard or too long knocks that air out and leaves a denser crumb.
Swap the orange
How well each one fits the dish's main ingredients (sugar, butter, milk, flour, egg):
- Vanillafits better
- Raisinfits better
- Figfits better
- Orangethe original
Fit is the average pairing score against sugar, butter, milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
