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 the meat
Remove the bone from the leg of mutton up to the first joint.
Roll bacon strips in mixed spices and minced savoury herbs.
Lard the inside of the boned leg.
Alternatively, 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
Add onions, carrots, bay leaves, savoury herbs, bones, and gravy.
Stew the meat gently for 4 to 5 hours.
Alternatively, place the braised leg in a 350°F (175°C) oven.
Glaze and serve
After cooking, strain the gravy.
Reduce the strained gravy to a glaze.
Brush the glaze over the meat.
Serve with boiled white beans or a mild ragout of garlic or eschalots underneath.

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 is cooked slowly until tender.
- Bacon
- Lards the meat and bastes it with fat, adding moisture and savoury flavour during braising.
- Onions
- Break down during braising to add sweetness and body to the gravy.
- Carrots
- Release sugars during slow cooking, adding sweetness and depth to the braising liquid.
- Gravy
- Provides the braising liquid, which keeps the meat moist and is later reduced to a glaze.
The step that matters
Stew the meat gently for 4 to 5 hours. Low, gentle heat lets the tough connective tissue in the mutton break down into gelatin, making the meat tender. Boiling hard toughens the muscle fibres and dries the surface.
Swap the onion
How well each one fits the dish's main ingredients (mutton, carrot):

Fit is the average pairing score against mutton, carrot. Candidates are from the same food group and used in at least 100 recipes.
