Why it works: Horseradish and roe work together. They rank in the top 13% of all ingredient pairs, and 43 recipes mention both. Both carry eugenol, which smells clove, spicy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carp
- The main fish, which becomes tender and flaky as it stews slowly in the gravy.
- Beef gravy
- Forms the savoury liquid base that carries the flavour through the stew.
- Port wine
- Adds sweetness and depth to the sauce as it simmers with the fish.
- Anchovies
- Contribute a deep savoury, salty flavour that enriches the gravy.
- Butter rolled in flour
- Thickens the gravy into a smoother, richer sauce when it boils.
The step that matters
Let the gravy boil after adding the butter and flour. Flour-thickened butter needs to reach a boil to fully cook the starch and thicken the sauce, otherwise the gravy can stay thin or taste floury.

Fit is the average pairing score against beef, onion, clove, pepper, port wine, mustard, ketchup. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
