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 ↓

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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
Cream the butter and gradually beat in the sugar until light.
Add the milk a little at a time and mix in the vanilla extract.
Beat the egg whites to a stiff froth.
Mix the baking soda and cream of tartar with the flour.
Stir the flour and egg whites alternately into the butter mixture.
Bake
Butter three tin pans and spread the batter evenly in them.
Bake in the preheated oven until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air and add richness and tender texture.
- Sugar
- Sweetens the cake and helps create a light, aerated creamed base.
- Egg whites
- Whipped to a stiff froth, they provide structure and lift to the batter.
- Flour
- Forms the main structure of the cake once mixed and baked.
- Baking soda
- Reacts with cream of tartar to release gas that makes the cake rise.
- Cream of tartar
- Acidifies the batter so baking soda produces gas, and stabilizes the whipped whites.
The step that matters
Stir the flour and egg whites alternately into the butter mixture.. Folding gently alternating dry and whipped ingredients keeps the air in the egg whites. Overmixing deflates the foam and toughens the gluten, leading to a dense cake.
