Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Flounders, Water Souchet
Ingredients
Directions
Prepare
Cut each flounder in half.
Cook
In a sauté pan, combine water, horseradish, pepper, salt, sugar, and parsley; bring to a boil.
Add the flounders and stew for 10 minutes.
Remove the flounders and place them in a dish without a napkin.
Reduce the cooking liquid slightly, then pour it over the flounders and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flounder
- Forms the main body of the dish, cooking gently to a tender, flaky texture in the liquid.
- Horseradish
- Adds a sharp, pungent aroma that flavours the cooking liquid.
- Parsley
- Contributes a fresh, herbal aroma to the cooking liquid.
The step that matters
Bring the liquid to a boil before adding the flounder. Adding the fish to liquid that is already simmering or boiling helps the flesh set quickly and stay tender, while the gentle stew finishes the cooking without toughening it.
Swap the horseradish
