Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten eggs trap air, giving the sponge its light, airy structure.
- Sugar
- Adds sweetness and helps give the sponge a tender crumb.
- Flour
- Provides the structure that holds the cake together as it sets.
- Cream of tartar
- Acidifies the batter, stabilising the beaten eggs and helping the cake rise.
- Soda
- Reacts with the acid in the batter to produce gas, aiding rise and lightness.
The step that matters
Roll while warm. A warm sponge is pliable enough to roll without cracking; once it cools it becomes brittle and splits. Rolling in a damp towel keeps it from sticking and cracking.
