Why it works: Lemon and tarragon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,137 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Ingredients
Directions
Prepare the base
Combine celery and herbs in a pot, cover, and simmer gently for 30 minutes.
Heat butter in a stew pan and fry the onion for 2 minutes until slightly colored.
Stir in enough flour to form a stiff paste, then gradually mix in the gravy from the bones.
Let it boil gently for 15 minutes until it thickens to a cream-like consistency.
Strain the mixture through a sieve into a basin.
Return the strained mixture to the stew pan.
Season and serve
Season with pickled onions, walnuts, gherkins, or capers.
Add mushroom ketchup or pickled liquor.
Cover the bottom of a serving dish with toasted bread sippets cut into triangles.
Garnish with fried bread sippets.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Gives the gravy its main flavour and, once simmered and strained, body and a vegetable base.
- Flour
- Forms a stiff paste with the butter that thickens the gravy as it boils.
- Butter
- Adds richness and fat, and helps soften and lightly colour the onion.
- Mushroom ketchup or pickled liquor
- Adds savoury depth and acidity to the finished gravy.
The step that matters
Boiling the flour-based gravy. Flour thickens only when it is cooked through at a gentle boil. Stirring it in smoothly before adding liquid and boiling gently for the full time prevents lumps and a raw, floury taste.
Swap the onion
How well each one fits the dish's main ingredients (celery, lemon, butter, flour, mushroom, tarragon, bread):
- Shallotfits better
- Asparagusfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against celery, lemon, butter, flour, mushroom, tarragon, bread. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
