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: milk, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare a brown turnip soup.
Mix in a large spoonful of tomatoes.

Pour the soup into a tureen containing small potato quenelles and parboiled chervil and tarragon leaves.
Serve with grated Parmesan cheese on the side.
