Why it works: Onion and allspice are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 4,270 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herring
- Forms the main body of the dish, and its oils and flesh carry the pickling flavour.
- Cold vinegar
- Acidifies and preserves the fish, firming its flesh as it pickles.
- Onion
- Adds sharp, sweet aroma that mellows during pickling.
- Whole allspice
- Adds warm, aromatic spice flavour to the pickling liquid.
- Bay leaves
- Contributes a subtle herbal aroma to the pickle.
The step that matters
Soaking the herring overnight. Soaking draws out excess salt from cured herring, so the fish tastes balanced rather than overly salty once it is pickled in vinegar.
Swap the onion
How well each one fits the dish's main ingredients (allspice, vinegar):
- Mustardfits better

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