Why it works: Pepper and lemon 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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- White fish
- Forms the main body of the dish and flakes into the sauce as it simmers.
- Butter
- Fat that carries the frying and adds richness and browning to the onions and fish.
- Flour
- Thickens the stock and wine into a smooth, lightly bodied sauce.
- Red wine
- Adds acidity and depth of flavour to the simmering sauce.
- White onions
- Become sweet and soft during frying, adding body and mild sweetness to the sauce.
The step that matters
Frying until golden brown. Browning the fish and onions in butter builds savoury, caramelised flavour through the Maillard reaction. Stopping too early leaves the base flat, while over-browning can taste bitter.
Swap the onion
How well each one fits the dish's main ingredients (fish, butter, mushroom, flour, pepper, lemon, red wine):
- Shallotfits better
- Spinachfits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against fish, butter, mushroom, flour, pepper, lemon, red wine. Candidates are from the same food group and used in at least 100 recipes.
