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 ↓
Layer 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
Preheat the oven to 400°F (200°C).
Cream the butter, then add lemon juice and egg yolks; beat until smooth.
Fold in the egg whites, one quarter at a time.
Mix in the milk, rose water, flour, corn starch, and baking powder until light.
Pour the batter into jelly‑cake pans and bake until light brown.
Make the icing
For the icing, boil powdered sugar and water, then add egg whites and cool.
Stir in vanilla sugar once the icing is cold.
Finish and decorate
To decorate, sprinkle each layer with grated coconut or use French icing.
For a Castle Cake, cream together 1 cup butter and 3 cups sugar, then add 1 cup milk.
Mix in baking powder and 4 cups flour, then fold in 10 beaten egg whites.
Layer with a thin coating of boiled icing and sprinkle with grated coconut.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- Flour
- Provides the structure that holds the cake's crumb together as it bakes.
- Egg whites
- Trap air when folded in, helping the layers rise and turn light.
- Butter
- Adds fat that makes the crumb tender and richly flavored.
- Baking powder
- Releases gas during baking, lifting the batter so the layers rise.
- Egg yolks
- Add richness and help bind the batter while adding color and flavor.
- Corn starch
- Softens the flour's gluten, giving a finer and more tender crumb.
The step that matters
Fold in the egg whites, one quarter at a time.. Whipped egg whites hold air that makes the batter light. Adding them in portions and folding gently keeps that air from being knocked out, so the layers rise well.
Swap the lemon
How well each one fits the dish's main ingredients (butter, egg, milk, rose, flour, corn, sugar):

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