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 says “a very moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the custard
Beat the eggs in a bowl.
Add flour, lemon rind, powdered sugar, orange flower water, and broken macaroons.
Pour the mixture into a saucepan with milk over low heat.
Stir continuously for 20 minutes until thickened.
Fill and bake
Line patty pans with puff pastry.
Pour the mixture into the lined pans and bake for 20 minutes at 350°F (175°C).

Flour and milk barely smell alike, yet cooks put them together in 78,219 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
- Eggs
- Set when heated, giving the filling its body and structure.
- Flour
- Starch thickens the liquid as it heats, helping the filling hold its shape.
- Milk
- Forms the liquid base that the eggs set into a smooth custard.
- Macaroons
- Add sweetness and a tender, crumbly texture to the filling.
- Lemon rind
- Adds bright citrus aroma and a touch of acidity.
- Orange flower water
- Adds a floral aroma that rounds out the citrus.
The step that matters
Stir continuously over low heat. Egg proteins set at a gentle heat, and if the mixture gets too hot or stands still, the eggs can curdle or scramble. Constant stirring keeps the heat even so the custard thickens smoothly.
Swap the orange
How well each one fits the dish's main ingredients (egg, flour, lemon, sugar, milk):
- Vanillafits better
- Raisinfits better
- Figfits about as well
- Orangethe original
Fit is the average pairing score against egg, flour, lemon, sugar, milk. Candidates are from the same food group and used in at least 100 recipes.
