Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give a tender, rich crumb.
- Sugar
- Creamed with butter to add sweetness and help hold air in the batter.
- Egg whites
- Beaten in to add lightness and structure as the cake rises and sets.
- Flour
- Gently stirred in to provide the structure that holds the cake together.
The step that matters
Stirring in the flour lightly. Overmixing once flour is added develops gluten, which toughens the crumb and can make the cake dense. Stir only until the flour is just combined.
