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 moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Mix all the ingredients together in a bowl.
Transfer the mixture to a buttered baking dish or custard cups.
Bake
Bake for about 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the main body of the loaf and gives it its flavor.
- Egg
- Binds the mixture and sets as it bakes, holding the loaf together.
- Bread crumbs
- Absorb the liquid and add body, keeping the loaf tender rather than dense.
- Milk
- Adds moisture, so the loaf stays soft and does not dry out in the oven.
- Lemon juice
- Adds acidity that brightens the flavor of the salmon.
The step that matters
Bake for about 20 minutes. The egg sets as the loaf bakes. Underbaking leaves the centre loose and wet, while overbaking dries the milk and crumbs out and makes the loaf tough. Check that it is set through before removing it from the oven.
Swap the onion
How well each one fits the dish's main ingredients (salmon, milk, lemon, bread, egg, pepper):
- Asparagusfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against salmon, milk, lemon, bread, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
