Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, giving the cake a tender crumb and moist texture.
- Sugar
- Sweetens the cake and helps keep the crumb tender and moist.
- Eggs
- Provide structure and richness, with the yolks adding fat and the whites adding lift.
- Flour
- Forms the structure that holds the cake's rise and shape as it sets.
- Baking soda
- Produces carbon dioxide gas when it meets an acid, which makes the batter rise.
- Cream of tartar
- Provides acidity that reacts with the baking soda to release gas for leavening.
The step that matters
Beat thoroughly. Baking soda releases carbon dioxide gas when it meets an acid such as cream of tartar. Beating the batter well spreads that gas evenly through it, and the gas is what lifts the cake.
