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
Clean the salmon thoroughly without soaking it in water.
Rub a little coarse sea salt into the body of the salmon.
Dust the salmon with flour and wrap it in a cloth, securing it with a pin.

Boil the salmon for about 30 minutes after the water returns to a boil.
Serve with drawn butter and eggs, lemon fish sauce, or pease pudding sauce.

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 is cooked gently by simmering in water.
- Flour
- Dusted on the wrapped fish, it helps form a thin coating that protects the surface during boiling.
- Eggs
- Used in the accompanying sauce, where they add richness and body.
- Drawn butter
- Adds fat and richness to the fish, carrying flavour in the sauce.
The step that matters
Boil the salmon for about 30 minutes after the water returns to a boil. Timing starts only once the water is boiling again, after the fish is added. Boiling too hard can break up the flesh, while too short a time leaves the centre underdone. Keeping the water at a steady simmer cooks the fish evenly.
