Why it works: Lemon and dill match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 976 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Ingredients
Directions
Prepare the herring

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Herring fillets
- Form the main body of the rolls, becoming tender and firm as they cure in the brine.
- Vinegar
- Acidifies the brine, which preserves the fish and gives the rolls their sharp, tangy flavour.
- Pickles
- Provide the core filling and a sour, crunchy contrast to the soft fish.
- Onion
- Adds sharp aromatic flavour that mellows as it sits in the pickling liquid.
The step that matters
Soaking the herring overnight. Soaking draws out excess salt from the fish, so the cured rolls taste balanced rather than overly salty once the brine has done its work.
Swap the onion
How well each one fits the dish's main ingredients (pepper, lemon, dill, vinegar):
- Mustardfits better
- Cucumberfits better
- Capsicumfits better
- Onionthe original
Fit is the average pairing score against pepper, lemon, dill, vinegar. Candidates are from the same food group and used in at least 100 recipes.
