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 together as it bakes.
- Cream of tartar
- Acidifies the batter so it reacts with soda to lift the cake.
- Soda
- Reacts with the acid in the batter to produce gas that makes the cake rise.
- Eggs
- Add structure and help bind the batter while adding richness.
- Butter
- Adds fat for tenderness and richness in the crumb.
The step that matters
Stir quickly and deftly. Once the soda and acid meet in the liquid batter, the gas they release starts escaping. Stirring briefly and gently keeps the air in, and overmixing toughens the gluten in the flour, giving a dense, tough cake.
