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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Grease gems or patty pans.
Make the batter
Cream butter and sugar together until light and fluffy.
Add egg yolks and beat until very light.
Beat egg whites to stiff peaks.
Fold egg whites into mixture alternately with flour.
Stir in lemon juice, lemon rind, and preserved lemon peel.
Beat mixture for several minutes until very light.
Bake and serve
Fill pans with batter.
Bake in preheated oven at 400°F (200°C) for 15 to 20 minutes.
Test for doneness with a broom whisk.
Cool on inverted sieve.
Ice with lemon icing if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg whites trap air for lift, while yolks add richness and help set the crumb.
- Butter
- Butter adds fat that tenderizes the crumb and carries flavour.
- Sugar
- Sugar adds sweetness and, creamed with butter, helps trap air in the batter.
- Flour
- Flour provides the structure that holds the cake's risen shape.
- Lemon
- Lemon juice adds acidity and the rind adds bright aroma.
- Preserved lemon peel
- Chopped peel adds concentrated lemon aroma and a slightly chewy texture.
The step that matters
Folding the egg whites into the batter. Fold gently, alternating with flour, so the air beaten into the whites stays in the batter. Overmixing deflates the foam and produces a dense, heavy cake.
