Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks enrich the batter, and whipped whites lighten it and help it rise.
- Flour
- Provides the structure that holds the cake's crumb once baked.
- Butter
- Adds fat for a tender texture and rich flavour.
- Sugar
- Sweetens the cake and helps creaming trap air in the batter.
- Sour milk
- Its acidity reacts with leavening and tenderises the crumb.
- Chocolate
- Gives the cake its chocolate flavour and deep colour.
The step that matters
Gently fold in the beaten egg whites. Whipped egg whites trap air that makes the cake rise. Stirring them vigorously deflates the foam, leaving a dense cake, so fold gently until just combined.
