Why it works: Horseradish and cucumber match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 640 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Boiled Salmon
Ingredients
Directions
Prepare the fish
Shape the fish into an 'S' by threading a string through the tail, center, and head, or fold it in a clean cloth if using a fillet.
Make two or three slanting gashes on each side to prevent the skin from breaking.
Boil and serve
Bring 4 quarts of water to a boil and add ½ cup of coarse sea salt to the boiling water.
Skim off any scum that rises to the surface.
Add the fish and a small piece of horseradish to the boiling water.
Boil for about 15 minutes per pound, until fully cooked.
Serve with lobster or white parsley sauce, garnished with sliced lemon, and accompanied by mashed potatoes and cucumbers sliced in vinegar.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Salmon
- Forms the main dish; poaching in gently simmering water cooks it evenly while keeping it moist.
- Horseradish
- Adds a sharp, pungent aroma that complements the mild flavor of the fish.
- Coarse sea salt
- Seasons the poaching water so the fish is lightly flavored as it cooks.
The step that matters
Skim off the scum. Scum is coagulated protein and impurities that rise as the water heats; removing it keeps the broth clear and the fish's surface clean. Skimming before adding the fish prevents residue from sticking to the flesh.
Swap the lemon
