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.
Sift the sugar three times and gradually add it to the butter, beating until creamy.
Mix in the milk and sifted flour combined with baking powder.
Beat well and gently fold in the stiffly beaten egg whites, adding them a little at a time.
Add the last cup of flour and mix until just combined.
Bake
Pour the batter into a tin and bake for 45 minutes in a moderate oven 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
- Butter
- Creams with sugar to trap air and add richness and tenderness to the crumb.
- White sugar
- Beaten with butter to create a creamy base and add sweetness and tenderness.
- Flour
- Provides the main structure that sets the cake as it bakes.
- Baking powder
- Releases gas during baking so the loaf rises and becomes light.
- Eggs
- Stiffly beaten whites add air and lift, and help set the structure.
- Milk
- Adds moisture and liquid that hydrates the flour and softens the crumb.
The step that matters
Folding in the egg whites. Stiffly beaten whites hold air that gives the loaf its lift. Adding them all at once or stirring vigorously deflates them, leaving a dense cake. Fold gently and add them a little at a time.
Swap the vanilla
How well each one fits the dish's main ingredients (butter, sugar, milk, flour, egg):
- Vanillathe original
- Raisinfits about as well
- Figfits less well
- Coconutfits less well
Fit is the average pairing score against butter, sugar, milk, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
