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 ↓
Gravies and Sauces
Ingredients
Directions
Prepare the flavour base
In a pot, combine celery and savory, cover, and simmer gently for 30 minutes.
In a stew pan, heat butter and fry the onion over high heat for 2 minutes until slightly colored.
Make the sauce
Stir in enough flour to form a stiff paste, then gradually mix in the gravy from the bones.
Let the mixture boil gently for 15 minutes until it thickens to a cream-like consistency.
Strain the sauce through a sieve into a basin, then return it to the stew pan.
Season with pickled onions, walnuts, gherkins, mushroom ketchup, capers, ale, or vinegar as desired.
Serve
Toast bread and cut it into triangles to serve as sippets, placing them at the bottom of the dish to soak up the gravy.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Celery
- Provides the main vegetable flavour and aroma of the sauce.
- Butter
- Adds richness and carries the flavour of the fried onion.
- Flour
- Thickens the gravy into a stiff paste and then a smooth, cream-like sauce.
- Gravy made from bones
- Forms the savoury liquid base that the sauce is built on.
- Onion
- Adds savoury sweetness and aroma after frying in butter.
The step that matters
Adding the gravy to the flour paste. Flour must be cooked into the butter and then mixed in gradually with the liquid. Adding it all at once or too quickly can leave lumps, while a stiff paste that is loosened slowly stays smooth and thickens evenly as it simmers.
Swap the onion
How well each one fits the dish's main ingredients (celery, lemon, butter, flour, mushroom, tarragon, bread):
- Shallotfits 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.
