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 ↓
Pickled Salmon
Ingredients
Directions
Prepare the salmon
Soak the salmon in water for 24 hours, changing the water occasionally.
Put the salmon in boiling water with a little vinegar until cooked, then let it cool.
Make the sauce
In a saucepan, stew the chopped onion in sweet oil until well done.
Combine the egg yolks, lemon juice, and flour in a bowl and beat well.
Pour the egg mixture over the fish when nearly done.
Add ginger, pepper, and coarse sea salt to taste, and stew for 3‑4 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Is the main protein that becomes the dish once cooked and dressed.
- Egg yolks
- Thicken the sauce as they set with gentle heat, giving it a smooth, rich body.
- Lemon juice
- Adds acidity that brightens the dish and balances the richness of the yolks and oil.
- Sweet oil
- Carries the flavour of the cooked onion and adds richness to the sauce.
- Flour
- Stabilises the egg mixture so it thickens smoothly rather than curdling.
The step that matters
Pour the egg mixture over the fish when nearly done.. Egg yolks thicken and can scramble if they get too hot or are added to a boiling liquid. Adding them near the end, off a hard boil, and beating well keeps the sauce smooth.
Swap the onion
How well each one fits the dish's main ingredients (salmon, vinegar, egg, lemon, flour, ginger, pepper):
- Shallotfits better
- Cucumberfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against salmon, vinegar, egg, lemon, flour, ginger, pepper. Candidates are from the same food group and used in at least 100 recipes.
