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 ↓
Delicious 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.
Make the cake batter
Preheat the oven to 350°F (175°C).
Beat the butter until creamy, then stir in the sugar.
Add the milk, then mix in the flour and beaten egg whites.
Divide the batter into two equal parts.
Grate half a cake of chocolate into one half of the batter.
Bake and make the custard
Pour the batter into cake pans and bake until done.
Melt 1 tablespoon of butter in a saucepan.
Add ½ pint of milk and bring to a boil.
Stir in 2 beaten eggs, 1 cup of sugar, and 2 teaspoons of cornstarch dissolved in a little milk.
Cook until thickened, then spread over the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Beaten whites trap air, helping the cake rise and giving it a light crumb.
- Butter
- Creamed with sugar, it traps air and adds tenderness and richness to the crumb.
- Sugar
- Sweetens the cake and helps create a tender texture when creamed with butter.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Baking powder
- Releases gas in the batter, causing the cake to rise.
- Chocolate
- Adds chocolate flavour and colour to one half of the batter.
The step that matters
Cook the custard until thickened. Cornstarch thickens only when the mixture reaches a boil and is stirred, so undercooking leaves it runny and it may not set properly when spread over the cake.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
