Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
White Cake
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
Beat the butter to a cream.
Add the sugar, flour, cornflour, milk, baking powder, and lemon flavor.
Lastly, add the well-beaten egg whites.
Bake
Bake immediately in a moderate oven at 350°F (175°C).

Flour and butter barely smell alike, yet cooks put them together in 124,287 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
- Egg whites
- Trap air when beaten, giving the cake a light, airy structure as it sets.
- Butter
- Creamed with sugar to hold air and add fat for a tender crumb.
- Sugar
- Sweetens the cake and helps it brown and keep a soft texture.
- Flour
- Provides the main structure that sets as the cake bakes.
- Cornflour
- Softens the crumb, giving a more tender texture than flour alone.
- Baking powder
- Releases gas in the batter, causing the cake to rise in the oven.
The step that matters
Bake immediately after mixing. Baking powder starts releasing gas once wet, and beaten egg whites slowly lose air. Delaying the oven weakens the rise. Fold the whites in gently so their trapped air stays in the batter.

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