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 until stiff peaks form.
Gradually fold the egg whites into the butter mixture, alternating with the flour.
Stir in the lemon juice, grated rind, and chopped lemon-peel.
Spoon the batter into buttered patty pans.
Bake and ice
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
- Butter
- Creamed with sugar to trap air and give the cake a tender, rich crumb.
- Eggs
- Yolks enrich the batter, and whipped whites add lift and a light, airy structure.
- All-purpose flour
- Provides the structure that sets the cake as it bakes.
- Sugar
- Creams with the butter for air and adds sweetness and golden browning.
- Preserved lemon-peel
- Adds concentrated, salty-sour citrus aroma and flavour throughout the cake.
The step that matters
Folding the egg whites into the butter mixture. Whites hold air that gives the cake its lift. Folding gently, alternating with flour, keeps that air in; vigorous stirring deflates the batter and produces a dense cake.
