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 ↓
Chocolate Cake
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Mix the butter and sugar together.
Make the batter
Add the egg yolks, melted chocolate, and milk.
In a separate bowl, beat the egg whites until stiff and mix in the baking soda.
Combine the flour with the cream of tartar, then add to the mixture along with the vanilla.
Bake
Pour the batter into a greased pan and bake for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites beaten to stiff peaks trap air, giving the cake structure and lift.
- Flour
- Flour forms the gluten and starch framework that sets the cake's crumb.
- Sugar
- Sugar adds sweetness and helps keep the crumb tender and moist.
- Baking soda
- Baking soda releases gas when it meets an acid, helping the cake rise.
- Butter
- Butter adds fat, which tenderizes the crumb and carries flavor.
- Cream of tartar
- Cream of tartar is an acid that stabilizes whipped egg whites and works with the baking soda.
The step that matters
Beating the egg whites until stiff. Whites must be beaten to stiff peaks without going dry or grainy, since they hold the air that lifts the batter. Folding gently afterward keeps that air from collapsing.
