Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Boiled Salmon
Ingredients
Directions
Prepare
Soak the salmon in salt water about ½ inch deep for 30 minutes.
Scrape the skin thoroughly to improve flavor and color.
Dip a thin cloth in boiling water, dredge it with flour, and wrap the fish.
Boil and serve
Place the wrapped fish in a pot with cold water to cover.
Boil for 20 minutes, adding 2 teaspoons of salt 5 minutes before it's done.
Transfer the fish to a platter, carefully remove the black skin, and pour drawn butter over it.
Garnish with sliced boiled egg and sprigs of parsley.

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, cooked gently in water until flaky.
- Flour
- Dusted on the cloth so the fish skin does not stick to it during boiling.
- Drawn butter
- Adds richness and a smooth, fatty coating that complements the mild fish.
The step that matters
Boil for 20 minutes, adding salt 5 minutes before the end. Boiling too hard or too long can toughen and dry the fish, so keep the water at a gentle simmer and check doneness near the end.
Swap the parsley
How well each one fits the dish's main ingredients (salmon, flour, butter, egg):
- Capersfits better
- Nutmegfits about as well
- Jalapenofits about as well
- Parsleythe original
Fit is the average pairing score against salmon, flour, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
