Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Salmon Loaf
Ingredients
Directions
Prepare the loaf
Chop the drained salmon finely.
In a bowl, mix the salmon, melted butter, beaten eggs, salt, bread crumbs, parsley, and red pepper until well combined.
Transfer the mixture into a well-buttered mold.
Steam and make the sauce
Steam the mold for 1½ hours.
For the sauce, melt 2 tablespoons of butter in a saucepan.
Stir in 2 tablespoons of flour and a dash of red pepper.
Gradually add the boiling milk and reserved salmon liquor, stirring until thickened.
Remove from heat and stir in a beaten egg.
Serve
Serve the sauce with the salmon loaf.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Butter and flour barely smell alike, yet cooks put them together in 124,287 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
- Eggs
- Bind the mixture and set the loaf as they cook.
- Bread crumbs
- Add body and soak up moisture so the loaf holds together.
- Salmon
- Forms the main body of the loaf and gives its flavour.
- Butter
- Adds richness and moisture to the loaf and enriches the sauce.
- Flour
- Thickens the sauce by absorbing the melted butter and liquid.
The step that matters
Gradually add the boiling milk. Adding hot liquid slowly to the butter and flour mixture while stirring prevents lumps, so the sauce thickens smoothly.
Swap the parsley
How well each one fits the dish's main ingredients (salmon, butter, egg, bread, pepper, sauce, flour):
- Capersfits better
- Parsleythe original
- Nutmegfits about as well
- Tarragonfits less well
Fit is the average pairing score against salmon, butter, egg, bread, pepper, sauce, flour. Candidates are from the same food group and used in at least 100 recipes.
