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 ↓
Lemon Cakes, or King Henry's Shoe Strings
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Beat the yolks of 6 eggs well.
Add ¾ pound sifted sugar, grated lemon rind, and 2 tablespoons orange‑flower water; mix well.
Slowly add 6 ounces of flour, then fold in the stiffly beaten egg whites and the juice of 1 lemon.
Bake and serve
Pour the mixture into ladyfinger tins or a large pan, spreading it very thin.
Bake in a slow oven at 300 °F (150 °C) for 1 hour.
Cut into strips.

Egg and flour barely smell alike, yet cooks put them together in 106,462 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
- Egg whites
- Whipped stiff, they trap air and give the cakes a light, airy structure.
- Egg yolks
- Beaten well with sugar, they add richness and help bind the batter.
- Flour
- Provides the structure that holds the thin cakes together as they set.
- Sugar
- Sweetens the cakes and helps create a tender crumb.
- Lemon juice
- Adds acidity and bright lemon flavour to the batter.
The step that matters
Folding in the egg whites. Stiffly beaten whites hold the air that lightens the cakes. Folding gently, rather than stirring, keeps that air from collapsing before the batter reaches the oven.
Swap the orange
How well each one fits the dish's main ingredients (egg, sugar, lemon, flour):
- Raisinfits better
- Vanillafits better
- Orangethe original
- Blueberryfits about as well
Fit is the average pairing score against egg, sugar, lemon, flour. Candidates are from the same food group and used in at least 100 recipes.
