Why it works: Chervil and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and 795 recipes mention both. Both carry estragole, which smells anise, licorice. The science ↓
The recipe
Ingredients
Contains: fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Clean and cut the herring fillets into dice.
In a bowl, combine the herring, diced cold boiled potatoes, diced russet apples, parsley, chervil, chopped fennel, and tarragon.
Season the mixture with oil, vinegar, coarse sea salt, and black pepper.
Shape the mixture to resemble herring.
Attach the reserved heads and tails at each end of the imitation herring.

Fit is the average pairing score against potato, parsley, chervil, fennel, tarragon, vinegar, pepper. 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).
