Ingredients

Directions

Prepare the leg

Trim the large end of the leg to make it flat and cut through the joint where it has been carved.

Bring to a boil, then add onions, parsley, hay leaves, carrots, and turnips.
Simmer gently for about 2 hours.
Add thickening, spices, or store sauce to the gravy as desired before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Leg of mutton: Forms the main body of the dish and provides the rich, meaty flavor of the braise.
Veal forcemeat: Fills the space left by the removed bone, adding moisture and a tender, cohesive texture.
Onions: Contribute sweetness and aromatic depth to the braising liquid as they soften.
Carrots: Add natural sweetness and body to the gravy as they cook slowly.
Turnips: Add mild sweetness and earthy flavor to the braising liquid and vegetables.

The step that matters

Simmer gently for about 2 hours. A gentle simmer lets connective tissue in the mutton break down slowly, giving tenderness. A rolling boil toughens the surface and clouds the gravy.

Swap the onion
