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.
Make the batter
Cream together the butter, sugar, lemon rinds, and mace until thick and smooth.
Add the eggs three at a time, then mix in the milk and rose-water until smooth.
Sift the baking powder with the flour and corn starch, then combine all ingredients and stir quickly until smooth.
Bake the cakes
Pour the batter into round cake pans to a depth of half an inch and bake at 350°F (175°C) until done.
Make the filling
For the filling, mix 6 oz sugar, 2 eggs, ⅓ cup caramel, 3 egg yolks, 1 tablespoon corn starch, and 1 pint milk until smooth.
Cook the mixture in a double boiler until it thickens to a custard.
Assemble and finish
Once cooled, spread a layer of custard on a sheet of cake, add a second layer, and top with a third sheet.
Dust the top with powdered sugar.

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
- Adds fat that gives the cake a tender, rich crumb when creamed with sugar.
- Sugar
- Sweetens the cake and helps hold air when creamed, adding lightness and browning.
- Eggs
- Provide structure as they set, and richness through their yolks and whites.
- Flour
- Forms the main structure of the cake as its proteins set during baking.
- Milk
- Adds moisture to the batter and sets the custard filling as it thickens.
- Corn starch
- Softens the crumb and thickens the custard filling when heated.
The step that matters
Cooking the custard in a double boiler. Egg proteins set at moderate heat and can curdle or scramble if overheated, so gentle, steady cooking in a double boiler keeps the custard smooth while it thickens.
Swap the mace
How well each one fits the dish's main ingredients (butter, sugar, lemon, egg, milk, rose, flour):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against butter, sugar, lemon, egg, milk, rose, flour. Candidates are from the same food group and used in at least 100 recipes.
