Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Yolks add richness and whites, beaten stiff and folded in, lighten the batter and give it structure.
Chocolate
Gives the cake its deep chocolate flavour and dark colour.
Flour
Provides the structure that holds the cake layers together as they set.
Baking powder
Releases gas in the batter, helping the cake rise and turn light.
Walnuts
Add crunch and nutty flavour to the filling.

The step that matters

Fold in the stiffly beaten whites. Folding gently keeps the air beaten into the whites. Deflating the batter by stirring hard makes the cake dense and flat instead of light.

Swap the walnut

How well each one fits the dish's main ingredients (egg, sugar, chocolate, milk, flour, vanilla):
