Why it works: Onion and parsley are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 25,843 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Marinated herring fillets
- Provide the main fish and its rich, savoury flavour and texture.
- Vinegar
- Adds acidity that sharpens the flavour and helps firm and preserve the fish.
- Sugar
- Balances the sharpness of the vinegar, rounding out the marinade.
- Juniper berries
- Contribute the resinous, aromatic flavour that defines this dish.
- Onions
- Add sharp, sweet crunch that contrasts with the soft, rich herring.
The step that matters
Chill the liquid well. The juniper liquid must be fully cold before it touches the fish, because warm liquid would start to cook and soften the herring and dull its texture.
Swap the parsley
How well each one fits the dish's main ingredients (onion, vinegar, sugar):
- Garlicfits better

- Parsleythe original
Fit is the average pairing score against onion, vinegar, sugar. Candidates are from the same food group and used in at least 100 recipes.
