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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Egg whites
- Whipped and folded in to add air and lift, so the cake rises and stays light.
- Egg yolks
- Add richness and emulsify the batter, helping it hold together smoothly.
- Flour
- Provides the structure that sets as the cake bakes.
- Baking powder
- Releases gas during baking, helping the cake rise.
- Chocolate
- Gives the cake its chocolate flavor and deep color.
The step that matters
Folding in the stiffly beaten egg whites. Stir gently with a folding motion so the whipped foam keeps its air. Vigorous stirring deflates the whites, and the cake bakes up denser and less light.
