Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herrings
- Form the main body of the dish, becoming firm and opaque as they cure in the acidic brine.
- Vinegar
- Acidity that preserves the fish and gives the pickled sharpness.
- Bay leaves
- Add aromatic flavour that infuses into the fish during pickling.
- Peppercorns
- Add a mild, warm pungency that seasons the fish as it pickles.
The step that matters
Letting the herrings sit for a few days. Acid from the vinegar needs time to penetrate the fish and firm its flesh. Serving too early leaves the fish soft and under-seasoned, so the pickling is incomplete.
Swap the clove
How well each one fits the dish's main ingredients (parsley, thyme, fennel, vinegar):
- Tarragonfits better
- Marjoramfits better
- Dillfits better
- Clovethe original
Fit is the average pairing score against parsley, thyme, fennel, vinegar. Candidates are from the same food group and used in at least 100 recipes.
