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 ↓
Caramel 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.
Prepare
Preheat the oven to 350°F (175°C).
Make the batter
In a bowl, rub together the butter, sugar, grated lemon rinds, and mace until you have a thick, smooth cream.
Add the eggs three at a time, mixing well after each addition.
Stir in the milk and rosewater, and knead the mixture until smooth.
Sift the baking powder through the flour and corn starch, then mix all ingredients together quickly until smooth.
Bake and finish
Pour the batter into round cake pans, filling them to a depth of half an inch.
Bake in the preheated oven until golden brown.
Ice with caramel icing once cooled.

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
- Butter
- Creams with sugar to trap air and adds richness and tender texture.
- Sugar
- Sweetens the cake and helps create a fine, creamed structure with the butter.
- Eggs
- Add structure and richness, binding the batter as it sets in the oven.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Baking powder
- Releases gas during baking so the cake rises and becomes light.
- Corn starch
- Softens the crumb, giving a more tender texture than flour alone.
The step that matters
Mixing in the eggs. Adding eggs too quickly can cause the creamed butter and sugar to separate, which may make the cake dense. Adding them gradually, mixing well after each, keeps the batter emulsified and smooth.
Swap the mace
How well each one fits the dish's main ingredients (butter, sugar, lemon, egg, milk, flour, corn):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against butter, sugar, lemon, egg, milk, flour, corn. Candidates are from the same food group and used in at least 100 recipes.
