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.
Make the batter
Cream the butter in a mixing bowl.
Gradually add the sugar and continue to cream together.
Add the eggs, two at a time, beating until perfectly smooth.
Mix in the milk and flour alternately.
Combine the baking powder with the last half cup of flour and sift it into the batter.
Add the orange and vanilla extracts.
Bake
Bake in a 350°F (175°C) oven for 40 to 50 minutes.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air, giving the cake a tender, rich crumb.
- Eggs
- Bind the batter and add structure and richness as they set in the oven.
- Baking powder
- Releases gas in the batter, helping the cake rise and turn light.
- Flour
- Forms the structure of the cake as its proteins set during baking.
- Sugar
- Adds sweetness and, creamed with butter, helps create a light texture.
The step that matters
Beating in the eggs. Adding eggs too quickly or while cold can cause the batter to curdle or separate. Adding them two at a time and beating until smooth keeps the emulsion stable, so the batter holds air and bakes evenly.

Fit is the average pairing score against butter, sugar, milk, flour, vanilla, egg. Candidates are from the same food group and used in at least 100 recipes.
