Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

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.
Make the dough
Cream the butter until smooth.
Mix in the powdered sugar, flour, salt, and lemon peel.
Beat the egg with the orange‑flower or rose‑water.
Knead the egg mixture into the dough until smooth.
Shape and bake
Roll out the dough and cut it into small rounds.
Bake on floured tins in a preheated oven at 400°F (200°C) for 15 to 30 minutes, depending on the size of the cakes.
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.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
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 give the cakes a tender, rich crumb and fat-based flavour.
- Egg
- Binds the dough and adds richness and structure to the cakes.
- Powdered sugar
- Sweetens the dough and dissolves smoothly into the creamed butter.
- All-purpose flour
- Provides the structure that holds the dough together once baked.
- Orange-flower water or rose-water
- Adds a floral aroma that flavours the dough.
The step that matters
Knead the egg mixture into the dough until smooth. Adding the egg to creamed butter can cause the mixture to separate if it is too cold or added too quickly. Kneading until smooth lets the egg emulsify fully, giving an even, tender dough.
