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 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the batter
Preheat the oven to 400°F (200°C).
Cream the butter thoroughly and beat in the sugar until light.
Add the egg yolks and beat until very light.
Beat the egg whites to stiff peaks and fold them in alternately with the flour.
Add the lemon juice, grated rind, and chopped lemon-peel; mix well.
Bake and ice
Drop the batter into buttered patty pans and bake for 15-20 minutes.
Immediately ice the cakes on the underside after removing from the oven.
To keep the cakes straight while icing, rest 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 trapped by whipping give the cakes lift, while the yolks add richness and tenderness.
- Butter
- Creaming with sugar traps air and adds fat for a tender, rich crumb.
- Sugar
- Sweetens the cake and helps create a light, airy texture when creamed with butter.
- All-purpose flour
- Provides the structure that sets the cake's crumb as the batter bakes.
- Preserved lemon-peel
- Adds concentrated lemon flavor and aroma, plus a slightly sharp, salty brightness.
The step that matters
Folding the whipped egg whites into the batter. Stiff whites hold the air that lifts the cake. Folding gently, alternating with flour, keeps that air from collapsing, so the cakes rise evenly and stay light.
