Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whisked and cooked with sugar, they build the structure and set the crumb.
- Butter
- Creamed to hold air and give the cake richness and a tender texture.
- Flour
- Provides the structure that holds the fruit and batter together as the cake sets.
- Powdered sugar
- Sweetens the batter and helps form a smooth, stable base with the eggs.
- Currants
- Add moisture, sweetness and fruity flavor throughout the cake.
The step that matters
Whisking the eggs and sugar over low heat. Gentle heat thickens the eggs without scrambling them. Too much heat can curdle or burn the mixture, so it must be stirred constantly and kept low.
