Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped to a stiff froth, they lighten the batter and give the cake its rise and airy structure.
- Egg yolks
- Beaten with sugar, they add richness and help bind the batter together.
- All-purpose flour
- Provides a small amount of starch that helps the layers hold their shape.
- Walnuts
- Supply the main body, nutty flavour and moisture of the cake.
- Blanched almonds
- Add bulk, delicate nutty flavour and a tender crumb to the layers.
The step that matters
Beat the egg whites to a stiff froth. Egg whites must be beaten until stiff but not dry, since they supply the air that leavens the nut batter. Under-beaten whites leave the cake dense, and over-beaten whites break down and weep.
