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 says “a good oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Add the well-beaten egg yolks and flour alternately.
Add the chocolate
Boil the milk and melt the chocolate in it.
Mix the chocolate mixture with the butter, egg yolks, and flour.
Finish and bake
Fold in the well-beaten egg whites.
Sift in the baking powder.
Bake in a preheated oven at 350°F (175°C) until done.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- All-purpose flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Eggs
- Egg yolks add richness and binding, while whipped whites trap air that lifts the batter.
- Butter
- Adds fat that tenderizes the crumb and carries flavor.
- Granulated sugar
- Sweetens the cake and helps the butter cream to a light, tender texture.
- Grated chocolate
- Gives the cake its chocolate flavor and adds richness and moisture.
- Baking powder
- Releases gas in the oven, helping the cake rise and become light.
The step that matters
Fold in the well-beaten egg whites. Fold gently with a spatula so the air bubbles in the whites stay intact. Stirring or beating hard deflates them, and the cake will rise less and bake up dense.
