Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Provide structure and moisture, helping the cake set and hold its rise.
- Butter
- Adds fat and richness, contributing to a tender crumb and flavor.
- Sugar
- Adds sweetness and, when creamed, helps trap air for a lighter texture.
- All-purpose flour
- Forms the main gluten structure that gives the cake its body.
- Rice flour
- Contributes a finer, more delicate crumb because it has little gluten.
The step that matters
Adding the eggs three at a time while stirring continuously. Eggs added too quickly can fail to emulsify into the butter and sugar, causing a curdled or greasy batter that bakes unevenly. Adding them gradually and stirring keeps the batter smooth and able to hold air.
