Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Add 1 cup of sifted flour mixed with 1 teaspoon of baking powder and 1 teaspoon of vanilla to the batter.
Fold in the stiffly beaten whites of the 4 eggs.
Bake and fill
Bake the batter in layer cake pans.
Beat 1 egg for the walnut filling and add 1 cup of milk, 1 tablespoon of sugar, and 1 cup of chopped walnuts.

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):
