Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and give the cake a tender crumb and rich flavor.
- Eggs
- Add structure and richness, and help bind the batter as they set.
- Flour
- Forms the main structure of the cake sheets as its proteins set when baked.
- Baking powder
- Releases gas in the batter so the cake sheets rise and stay light.
- Egg whites
- Whipped to stiff peaks, they give the raspberry filling lightness and volume.
- Raspberries
- Add tart, fruity flavor and moisture to the filling.
The step that matters
Beat the egg whites until stiff. Egg whites must be whipped to firm peaks before the raspberries are folded in. Under-whipped whites collapse and make the filling runny, while over-whipped whites turn dry and grainy.
