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

What each ingredient does

Leg of mutton: Provides the main cut of meat, which becomes tender and flavorful during long, gentle simmering.
Veal forcemeat: Fills the space left by the removed bone, adding moisture and a soft, rich texture to the meat.
Onions: Add aromatic sweetness and depth to the cooking liquid that flavors the meat and gravy.
Carrots: Contribute natural sweetness and color to the pot and the served vegetables.
Turnips: Add mild earthy flavor and a tender texture after simmering with the meat.

The step that matters

Simmer gently for nearly 2 hours. A gentle simmer lets connective tissue slowly break down into gelatin, making the meat tender and moist. A hard boil toughens meat proteins and can leave the outside tight and dry, so keep the liquid barely moving.
