Why it works: Onion and mustard match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 9,259 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Canned Salmon, Deviled
Ingredients
Directions
The book gives no oven temperature. The 400°F in the steps was added when the recipe was transcribed, as a starting point.
Make the sauce
Fry the onion until brown.
Add water, flour, English mustard, salt, and pepper; simmer.
Stir in the liquor from the can of salmon, being careful not to let it burn.
Assemble and bake
Place the hot salmon on a dish and spread the thick sauce over it.
Set it in a hot oven (400°F / 200°C) for a moment to brown the surface.

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, giving the sauce a flaky base to coat.
- Flour
- Thickens the liquid into a sauce that clings to the salmon.
- Onion
- Browning releases sweet, savoury flavours that deepen the sauce.
- English mustard
- Adds sharp, pungent heat that cuts through the richness of the fish.
The step that matters
Stirring in the salmon liquor while simmering. Flour-thickened sauces scorch easily on the bottom of the pan. Keeping the heat moderate and stirring constantly prevents burnt flavour and keeps the sauce smooth and even.
Swap the onion
