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.
Stir in the sugar and beat until light.
Add the milk.
Gradually mix in the flour and beaten egg whites.
Divide the batter in half.
Grate the sweet chocolate into one half.
Bake the cakes
Pour the batters into prepared cake pans.
Bake until a toothpick comes out clean.
Make the custard
Heat 1 pint of milk with 1 tablespoon of butter until boiling.
Beat 2 eggs with 1 cup of sugar.
Stir into the boiling milk.
Dissolve 2 teaspoons of corn starch in a little milk.
Add to the mixture, stirring until thickened.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites
- Whipped into the batter to give the cake its light, airy structure.
- Butter
- Creamed with sugar to add tenderness and richness to the cake.
- Flour
- Forms the main structure of the cake once set by heat.
- Baking powder
- Releases gas in the batter so the cake rises during baking.
- Sweet chocolate
- Adds chocolate flavour and color to one half of the batter.
- Corn starch
- Thickens the custard as it heats so it becomes smooth and set.
The step that matters
Stirring the custard as it thickens. Egg and starch mixtures can scorch on the bottom or curdle if heated unevenly. Constant stirring spreads heat and lets the starch thicken smoothly before the eggs overcook.
