Why it works: Butter and flour 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 ↓
Little Pound Cakes, with Preserved Lemon-peel
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Preheat the oven to 350°F (175°C).
Cream the butter and sugar together until light and fluffy.
Add the egg yolks and beat until well combined.
In a separate bowl, beat the egg whites to stiff peaks.
Alternately fold the egg whites and flour into the butter mixture.
Stir in the lemon juice, grated rind, and chopped lemon-peel.
Bake and ice
Spoon the batter into buttered patty pans.
Bake for 15 to 20 minutes until golden.
Immediately ice the cakes on the underside after removing from the oven.
To keep the cakes straight while icing, place them on thin strips of wood over a sieve until the icing hardens.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whites beaten to stiff peaks trap air, giving the cake a light, airy structure.
- Butter
- Creamed with sugar, it traps air and adds richness and a tender crumb.
- Sugar
- Creamed with butter, it helps create a light texture and adds sweetness.
- All-purpose flour
- Its proteins set when baked, forming the cake's main structure.
- Preserved lemon-peel
- Adds concentrated lemon aroma and a tangy, slightly salty flavour.
The step that matters
Folding the egg whites into the batter. Whites hold air only when stiff and gentle folding keeps it in. Overmixing deflates the batter, leading to a dense cake.
