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.
- Eggs
- Add structure and richness, helping the batter set and hold its shape.
- Baking powder
- Releases gas in the batter, making the cake rise and become light.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Sugar
- Sweetens the cake and helps keep the crumb tender and moist.
- Cocoa
- Gives the cake its chocolate flavor and deep brown color.
