Why it works: Sauce and ketchup match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Dressed Fish
Ingredients
Directions
Stew the fish slowly in enough fish liquor to cover them, along with the parsley, horseradish, and sauces.
Once the fish are cooked, place them in a deep dish.
Strain the cooking liquor over the fish. If there isn't enough liquor left, add a little more to cover the fish.
Garnish with chopped parsley before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooking gently to stay tender in the stewing liquor.
- Fish liquor
- Provides the cooking medium and savory base, keeping the fish moist as it stews.
- Parsley plants
- Add herbal aroma and flavor to the stewing liquor as the roots and leaves cook.
- Horseradish
- Contributes a sharp, pungent heat that mellows during slow stewing.
The step that matters
Stew the fish slowly. Gentle, slow heat cooks the fish through while keeping its flesh tender and intact. Vigorous boiling can toughen the protein and break the fish apart.
Swap the walnut
How well each one fits the dish's main ingredients (fish, parsley, horseradish, vinegar, sauce, ketchup):
- Beansfits about as well
- Walnutthe original
- Chestnutfits about as well
- Peasfits less well
Fit is the average pairing score against fish, parsley, horseradish, vinegar, sauce, ketchup. Candidates are from the same food group and used in at least 100 recipes.
