Directions

Prepare the base

  1. Combine celery and herbs in a pot, cover, and simmer gently for 30 minutes.

  2. Heat butter in a stew pan and fry the onion for 2 minutes until slightly colored.

  3. Stir in enough flour to form a stiff paste, then gradually mix in the gravy from the bones.

  4. Let it boil gently for 15 minutes until it thickens to a cream-like consistency.

  5. Strain the mixture through a sieve into a basin.

  6. Return the strained mixture to the stew pan.

Season and serve

  1. Season with pickled onions, walnuts, gherkins, or capers.

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):

  1. Shallotfits better
  2. Asparagusfits better
  3. Leekfits better
  4. 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.
