Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Cut off a piece of pastry for decoration and roll out the remainder into a square.
Wet the edges of the pastry square.
Make and fill
In a bowl, mix the cold meat, hard-boiled eggs, boiled rice, lemon juice, curry salt, pepper, and cayenne.
Season the filling well and place it on one half of the pastry.
Add a layer of chopped egg on top of the filling.
Bake and serve
Fold the pastry over, seal the edges, and decorate the top.
Brush the top with beaten egg.
Bake for 35 to 40 minutes.

Egg and lemon barely smell alike, yet cooks put them together in 44,316 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
- Cold meat
- Forms the bulk of the filling and provides the main savoury flavour.
- Hard-boiled eggs
- Add richness and body to the filling.
- Boiled rice
- Absorbs juices and helps bind and soften the filling.
- Flaky pastry
- Forms a crisp, layered shell that encloses the filling.
- Lemon juice
- Adds acidity that brightens the flavour of the rich filling.
The step that matters
Seal the edges of the pastry. Wetting and sealing the edges keeps the filling enclosed while baking; a poor seal lets juices escape and leaves the filling dry or the pastry soggy.
Swap the lemon
How well each one fits the dish's main ingredients (meat, egg, rice, pepper):
- Lemonthe original
- Limefits about as well
- Coconutfits about as well
- Avocadofits less well
Fit is the average pairing score against meat, egg, rice, pepper. Candidates are from the same food group and used in at least 100 recipes.
