Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to trap air and give the cake a rich, tender crumb.
- Eggs
- Add structure and richness, and help bind the batter as it sets in the oven.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Fine powdered sugar
- Sweetens the cake and helps the butter cream to a light, smooth batter.
- Currants
- Add fruit sweetness and chewy texture throughout the cake.
The step that matters
Adding the eggs gradually. Adding eggs slowly while beating keeps the batter emulsified. If eggs are added too fast, the batter can curdle and trap less air, leading to a denser cake.
Swap the currant
How well each one fits the dish's main ingredients (sugar, butter, egg, flour):
