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 Mountain Cake
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 until smooth.
Add the lemon juice, lemon rind, mace, and beaten egg yolks; mix well.
Whisk the egg whites until stiff peaks form, then fold in one-third at a time.
Stir in the milk and rose water gradually.
Sift together the flour, corn starch, and baking powder, then fold into the mixture until well combined.
Bake
Pour the batter into well-buttered jelly-cake pans to a depth of half an inch.
Bake in a preheated oven at 400°F (200°C) until light brown.

Butter and flour 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
- Whipped to stiff peaks, they lighten the batter and give the cake its rise and airy crumb.
- Egg yolks
- Add richness, fat and emulsifying power that help bind the batter and tenderize the crumb.
- Butter
- Creamed with sugar to trap air and add fat for a tender, rich texture.
- Flour
- Provides the structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter, helping the cake rise in the oven.
- Sugar
- Sweetens the cake and helps create a light, creamed base when beaten with butter.
The step that matters
Folding in the egg whites. Whites whipped to stiff peaks hold the air that lightens the batter. Adding them one-third at a time and folding gently, rather than stirring, keeps that air from collapsing so the cake rises well.
Swap the mace
How well each one fits the dish's main ingredients (sugar, butter, lemon, egg, milk, rose, flour):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against sugar, butter, lemon, egg, milk, rose, flour. Candidates are from the same food group and used in at least 100 recipes.
