Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whipped whites give the cake lift and an airy, light crumb; yolks add richness.
- Butter
- Creamed with sugar, it traps air and adds fat for a tender texture.
- Flour
- Provides the structure that holds the cake together as it sets.
- Sugar
- Sweetens the cake and helps cream with butter to hold air bubbles.
- English walnut kernels
- Add crunch, nutty flavor, and some fat to the crumb.
The step that matters
Fold in walnut pieces and whipped whites gently. Folding keeps the air trapped in the whipped egg whites, so the cake stays light instead of dense after steaming.
Swap the walnut
