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 says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the sauce
Fry the onion until brown.
Add water, flour, mustard, salt, and pepper; simmer.
Stir in the liquid from the canned salmon, being careful not to let it burn.
Assemble and singe
Place the hot salmon on a dish and spread the thick sauce over it.
Put it in a 400°F (200°C) oven for a moment to singe the surface.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Canned salmon
- Forms the main body of the dish and supplies the fish and its liquid for the sauce.
- Flour
- Thickens the sauce so it can coat the salmon rather than run off.
- Onion
- Browning in the pan builds savory, sweet flavor into the sauce.
- English mustard
- Adds sharp, pungent heat that cuts through the richness of the fish and sauce.
The step that matters
Stir in the salmon liquid without letting it burn. Flour and browned onion can scorch on direct heat, producing bitter, burnt flavors. Keeping the heat moderate and stirring constantly keeps the sauce smooth and tasting clean.
Swap the onion
How well each one fits the dish's main ingredients (flour, mustard, pepper, salmon):
- Horseradishfits better
- Chivefits better
- Shallotfits better
- Onionthe original
Fit is the average pairing score against flour, mustard, pepper, salmon. Candidates are from the same food group and used in at least 100 recipes.
