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. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, cream together the butter and sugar.
Beat the egg whites until frothy and add them to the butter mixture.
In a separate bowl, combine the flour, cream of tartar, and baking soda.
Gradually add the dry ingredients to the butter mixture, alternating with the milk.
Stir in the lemon and vanilla extracts.
Bake
Pour the batter into a greased cake pan and bake for 25–30 minutes or until a toothpick comes out clean.

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 adds richness and tender texture.
- Sugar
- Sweetens the cake and helps hold air when creamed with butter for a tender crumb.
- Egg whites
- Add structure and lift through the foam they form when beaten.
- Flour
- Provides the main structure that sets as the cake bakes.
- Cream of tartar
- Stabilizes the beaten egg whites and works with baking soda to help the cake rise.
- Baking soda
- Reacts with the acidic ingredients to produce gas that helps the cake rise.
The step that matters
Adding the dry ingredients alternately with the milk. Adding flour in portions alternating with liquid keeps the batter emulsified and limits gluten development, so the cake stays tender rather than tough or dense.
