Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Chocolate Cake
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the cake
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the sweet milk and mix well.
Sift together the flour and baking powder, then gradually add to the mixture.
Fold in the egg whites gently.
Divide the batter evenly among 4 round cake tins.
Bake for 25-30 minutes or until a toothpick comes out clean.
Make the filling
For the filling, melt the chocolate in a saucepan.
Stir in 1 cup sugar, 1 tablespoon flour, 1 cup milk, and 1 egg.
Cook until thick, then let it cool slightly and stir in coconut.
Assemble
Spread the filling between the cake layers, frost the top, and sprinkle with coconut.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with the sugar to add tenderness and a fine, light crumb.
- Egg whites
- Whipped structure that lifts the batter and sets the crumb as it bakes.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the batter so the cake rises and becomes light.
- Sugar
- Sweetens the cake and helps it brown and stay moist.
- Egg
- Thickens the chocolate filling as it cooks, giving it body.
The step that matters
Cook the filling until thick. Egg and flour thicken as they heat, but overheating can curdle the egg. Cook gently and stir constantly so the filling sets smooth rather than grainy or lumpy.

Fit is the average pairing score against butter, sugar, milk, flour, egg, chocolate. Candidates are from the same food group and used in at least 100 recipes.
