Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Pound-cake
Ingredients
Directions
The book says “a quick oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Line loaf tins with well-greased paper.
Make the batter
Beat the butter until creamy.
Stir the flour into the butter.
Beat the egg yolks and sugar together until very light.
Mix the yolk and sugar mixture with the butter and flour.
Add the lemon juice, lemon rind, and ground mace.
Beat the egg whites until stiff and fold them into the mixture.
Bake
Bake in a moderate oven at 350°F (175°C) for about 30 minutes.
Test for doneness with a broom whisk.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creamed with sugar, it traps air and gives the cake its rich, tender crumb.
- Eggs
- Yolks add richness and emulsify the batter, while whipped whites add lift and structure.
- Flour
- Its proteins set during baking, giving the cake its firm structure.
- Sugar
- Sweetens the cake and, creamed with butter, helps create a fine, tender texture.
- Lemon
- Its rind adds aroma and its juice adds a bright acidity that balances the sweetness.
The step that matters
Fold in the stiff egg whites. Folding gently keeps the air in the whipped whites. Overmixing or stirring vigorously deflates the batter, which leads to a dense, heavy cake with less rise.
Swap the mace
How well each one fits the dish's main ingredients (flour, sugar, butter, lemon, egg):
- Cinnamonfits better
- Nutmegfits better
- Parsleyfits better
- Macethe original
Fit is the average pairing score against flour, sugar, butter, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
