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 ↓
Chocolate Pies
Ingredients
Directions
Prepare the cake
Bake the plain cake in shallow dishes until thick enough to split.
Once cooled, split the cake in half.
Make the filling
Mix the chocolate and sugar together for the filling.
Slowly add the boiling milk and then the egg yolks, stirring continuously.
Simmer the mixture for 10 minutes, ensuring it does not burn.
Add vanilla flavor and let the filling cool completely before using.
Assemble
Spread the filling on one half of the cake, place the top piece on, and sprinkle with powdered sugar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Plain cake
- Forms the sponge base that holds the filling in layers.
- Chocolate
- Provides the main flavour and richness of the filling.
- Sugar
- Sweetens the filling and helps it set smooth as it cooks.
- Egg yolks
- Thicken the filling as they cook and add richness.
- Boiling milk
- Melts the chocolate and loosens the filling into a smooth mixture.
The step that matters
Simmering the filling. Egg yolks thicken only when heated gently; if the mixture gets too hot or boils hard, the yolks can scramble and the chocolate filling can catch and burn. Keep the heat low and stir steadily.
