Why it works: Milk and butter 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 ↓
Birthday Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Make the batter
Cream the butter and sugar together.
Add the beaten egg yolks.
Mix the dry ingredients and sift them 3 or 4 times.
Add the dry mixture to the creamed mixture along with the milk and stir well.
Fold in the beaten egg whites.
Fill and bake
If making a loaf cake, line a deep cake tin with buttered paper.
Layer the batter in the tin, sprinkling with chopped figs and black walnut meats between layers.
Fill the tin about ⅔ full.
Bake in a slow oven at 300°F (150°C) for about 40 minutes.
Finish
Frost with cream frosting and decorate with candies.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks enrich the batter, and whipped whites add lift and a light, airy crumb.
- Flour
- Provides the structure that holds the cake together as it bakes.
- Butter
- Creamed with sugar, it traps air and adds richness and tender texture.
- Sugar
- Sweetens the cake and helps create a tender crumb when creamed with butter.
- Baking powder
- Releases gas in the batter so the cake rises during baking.
- Milk
- Adds moisture and loosens the batter to a smooth, pourable consistency.
The step that matters
Fold in the beaten egg whites. Egg whites hold air that gives the cake its lift. Stirring them vigorously deflates the foam, so fold gently until just combined.
Swap the mace
How well each one fits the dish's main ingredients (sugar, flour, milk, butter, egg):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Macethe original
Fit is the average pairing score against sugar, flour, milk, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
