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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Dissolve the chocolate in 5 tablespoons of boiling water.
Beat the butter until creamy, then gradually add the sugar while continuing to beat.
Add the egg yolks and beat again.
Mix in the melted chocolate and milk, then add the flour.
Beat the mixture vigorously, then gently fold in the stiffly beaten egg whites.
Add the vanilla and pour the batter into a greased pan.
Bake
Bake for 45 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites trap air for lift, while yolks add richness and help bind the batter.
- Flour
- Provides the structure that holds the cake's crumb once baked.
- Butter
- Adds fat that makes the crumb tender and rich.
- Sugar
- Sweetens the cake and helps make the creamed butter light and tender.
- Baking powder
- Releases gas in the batter to make the cake rise.
- Chocolate
- Gives the cake its chocolate flavor and deep color.
The step that matters
Folding in the egg whites. Egg whites hold air that gives the cake its lift. Stirring or folding them too hard knocks that air out, so the cake bakes up denser and flatter.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
