Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Buttermilk
- Provides acidity that reacts with baking soda to lift the batter and adds tangy flavor.
- Baking soda
- Reacts with the acidic buttermilk to release carbon dioxide, helping the cakes rise.
- Eggs
- Yolks add richness and structure, while whipped whites give the cakes a light, airy texture.
- Flour
- Forms the structure of the batter so the cakes hold their shape while cooking.
The step that matters
Folding in the beaten egg whites. Whites hold air only while whipped, so folding them in gently keeps the batter light. Stirring vigorously knocks out the air and leaves the cakes dense.
