Why it works: Vinegar and horseradish are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 2,609 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Boiling Fish
Ingredients
Directions
Prepare the poaching liquid
Fill a large kettle with enough water to cover the fish.
Add salt, vinegar, horseradish, and sweet herbs to the water.
Boil the mixture for some time to infuse the flavors.
Remove the water and let it cool completely.
Poach the turbot
Score the turbot through the skin on the white side.
Place the fish in the kettle, dark side down.
Bring the water to a boil, then reduce the heat to maintain a gentle boil.
Skim off any foam that forms on the surface.
Boil the turbot for about 20 minutes.
Drain and serve
Drain the fish well and place it on a napkin over a fish drainer.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turbot
- Is the main protein, whose delicate flesh turns firm and flaky as it cooks gently in liquid.
- Vinegar
- Adds sharp acidity that brightens the mild flavor of the fish and the poaching liquid.
- Horseradish
- Adds a pungent, sharp aroma that flavors the poaching liquid.
- Sweet herbs
- Add gentle aromatic flavor to the poaching liquid as it infuses.
The step that matters
Keep the water at a gentle boil. A hard, rolling boil can break up the delicate fish and make the liquid cloudy. Skimming off the foam keeps the surface clear and stops residue from clinging to the fish.

Fit is the average pairing score against vinegar, turbot. Candidates are from the same food group and used in at least 100 recipes.
