Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Braised Leg of Mutton
Ingredients
Directions
Prepare the pot
Line the bottom of a thick iron kettle or stew-pan with 2 slices of bacon.
Place the sliced carrots, onions, and savory herbs over the bacon.
Put the leg of mutton on top, cover with the remaining bacon slices, and pour in the water.
Stew and season
Cover tightly and stew gently for 4 hours, basting occasionally with the juices.
Season with salt and pepper when the meat begins to tenderize.
Make the gravy and serve
Strain the gravy, thicken with flour until brown, and pour some over the meat.
Serve the remaining gravy in a tureen.
Garnish the dish with fried olive-shaped potatoes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Leg of mutton
- Is the main cut of meat that becomes tender through slow, moist stewing.
- Bacon
- Adds fat and savoury flavour that enriches the juices as they cook.
- Carrots
- Add sweetness and body to the braising liquid as they soften.
- Onions
- Add sweetness and depth of flavour to the braising liquid as they soften.
- Flour
- Thickens the strained gravy and helps it brown.
The step that matters
Keeping the stew gently simmering. Gentle, low heat over a long time breaks down connective tissue in the meat slowly; boiling vigorously toughens the muscle fibres and can dry the meat. Covering tightly keeps moisture in the pot.
