Why it works: Pepper and shallot are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 5,898 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

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 dish and provides the flesh that sets firm when poached.
- Vinegar
- Adds acidity to the poaching liquid, brightening the flavour of the fish.
- Bay leaves
- Contribute an aromatic herbal flavour to the poaching liquid.
- Shallot
- Adds a mild onion-like aroma to the poaching liquid.
The step that matters
Simmer gently for one hour. Boiling rather than simmering toughens and breaks up the salmon proteins, so the fish turns dry and ragged. A gentle simmer cooks it evenly and keeps the flesh moist and intact.
Swap the mace
How well each one fits the dish's main ingredients (salmon, pepper, vinegar, shallot):
- Capersfits better
- Tarragonfits better
- Dillfits better
- Macethe original
Fit is the average pairing score against salmon, pepper, vinegar, shallot. Candidates are from the same food group and used in at least 100 recipes.
