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 quick oven”. The 400°F (200°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 beaten egg yolks and mix well.
Dissolve the baking soda in the milk and add it to the mixture.
Alternate adding the flour and sifted cream of tartar, mixing until combined.
Fold in the beaten egg whites and add the vanilla extract.
Bake
Drop spoonfuls of the batter onto buttered baking sheets.
Bake in a preheated oven at 400°F (200°C) until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Provides the structure that holds the cookies together as they bake.
- Butter
- Adds richness and tenderness, and helps the cookies brown.
- Sugar
- Creams with the butter for tenderness and adds sweetness and browning.
- Eggs
- Yolks add richness and binding; whites, folded in, add lift and airiness.
- Cream of tartar
- Adds acidity that reacts with baking soda to help the cakes rise.
- Baking soda
- Reacts with the acidic cream of tartar to produce gas that leavens the batter.
The step that matters
Fold in the beaten egg whites. Egg whites hold air that gives lift. Folding gently keeps that air in; stirring hard deflates the batter and yields dense cakes.
