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 butter until creamy.
Add sugar and beat until light.
Mix in milk.
Gradually add flour and beaten egg whites.
Grate half a cake of sweet chocolate into batter. Mix well.
Divide batter into two equal parts.
Bake and make the custard
Bake in layers.
Heat 1 tablespoon butter with 1 pint milk until boiling.
Mix 2 beaten eggs, 1 cup sugar, and 2 teaspoons cornstarch dissolved in a little milk.
Add egg mixture to boiling milk. Stir until thickened.

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 trap air, giving the cake a light, tender crumb.
- Egg whites
- Whipped into the batter to add structure and lift as the cake sets in the oven.
- Flour
- Provides the main structure that holds the cake together as it bakes.
- Baking powder
- Releases gas during baking so the cake rises and becomes airy.
- Sweet chocolate
- Adds chocolate flavor and color to the batter.
- Eggs
- Thicken the custard as they cook in the hot milk, giving it body.
The step that matters
Stir until thickened. Egg mixture added to boiling milk can scramble if heat is too high or stirring stops. Constant stirring lets the cornstarch and egg thicken the custard evenly and smoothly.
