Why it works: Onion and carrot are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Braised Leg of Mutton
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Remove the bone from the leg of mutton as far as the first joint.
Roll strips of bacon in mixed spice and minced savoury herbs, then lard the inside of the boned joint.
Optionally, fill the cavity with highly seasoned forcemeat.
Sew up the meat and place it in a braising pan with bacon slices underneath and on top.
Braise and finish
Add onions, carrots, bay leaves, savoury herbs, bones, and gravy.
Stew the meat gently for 4 to 5 hours, keeping embers on top or placing it in a 350°F (175°C) oven.
Lift out the meat, strain the gravy, and reduce it to a glaze, brushing it over the meat.
Alternatively, strain the gravy, remove fat, and pour it over the mutton.

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, becoming tender through long, slow braising.
- Bacon
- Adds fat and savoury flavour that bastes the meat as it cooks.
- Onions
- Add sweetness and savoury depth to the braising liquid as they soften.
- Carrots
- Add sweetness and body to the braising liquid as they cook down.
- Gravy
- Provides the cooking liquid that keeps the meat moist and forms the glaze.
The step that matters
Stewing the meat gently for 4 to 5 hours. Low, steady heat lets the tough connective tissue in the mutton break down into gelatin, making the meat tender. Boiling or rushing the heat can toughen the muscle fibres and dry the surface.
