Ingredients
Directions
Make the gravy
Slice the onion and fry it in butter over high heat for 2 minutes until it colors slightly.
Stir in enough flour to form a stiff paste.
Gradually mix in the gravy made from bones and let it boil gently for 15 minutes until thick like cream.
Strain the mixture through a sieve into a basin and return it to the stewpan.
Season and serve
Season with pickled onions, walnuts, gherkins, mushroom catsup, ale, shallot, or tarragon vinegar as desired.
Cover the bottom of the dish with toasted bread snippets cut into triangles.
Garnish with fried bread snippets.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onion
- Softens and sweetens as it fries, adding savory depth to the gravy base.
- Butter
- Adds fat and rich flavor while helping the onion brown slightly.
- Flour
- Thickens the gravy into a smooth, stiff paste that gives body when liquid is added.
- Gravy made from bones
- Provides the main liquid and meaty flavor that the sauce is built on.
- Mushroom catsup
- Adds concentrated savory, umami flavor to the finished sauce.
The step that matters
Gradually mix in the gravy made from bones. Adding the liquid slowly to the flour paste lets it blend smoothly; adding it all at once can leave lumps that a sieve must then remove.
