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 ↓
Half Pound 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 the butter and powdered sugar together.
Add the beaten egg yolks, then mix in the milk and sifted flour with baking powder and mace.
Finally, fold in the beaten egg whites.
Bake
Pour the batter into a greased pan and bake at 350°F (175°C) for 50 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Yolks add richness and structure, while whipped whites lighten the batter and help it rise.
- Flour
- Provides the main structure that sets as the cake bakes.
- Baking powder
- Releases gas in the batter so the cake rises in the oven.
- Powdered sugar
- Sweetens the batter and, creamed with butter, helps create a light texture.
- Milk
- Adds moisture and helps form a smooth, pourable batter.
The step that matters
Folding in the beaten egg whites. Egg whites hold air bubbles that give the cake lift. Stirring them in vigorously knocks that air out, so fold gently with a spatula until just combined.
Swap the mace
How well each one fits the dish's main ingredients (butter, sugar, egg, milk, flour):
- Cinnamonfits better
- Nutmegfits better
- Jalapenofits better
- Macethe original
Fit is the average pairing score against butter, sugar, egg, milk, flour. Candidates are from the same food group and used in at least 100 recipes.
