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
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat your oven to 300°F (150°C).
Line the bottom of a thick iron kettle or stewpan with a few slices of bacon.
Layer the sliced carrots, onions, and savory herbs over the bacon.
Place the leg of mutton on top of the vegetables.
Cover the mutton with a few more slices of bacon and pour in ½ pint of water.
Braise and finish
Cover tightly and stew gently for 4 hours, basting occasionally with the juices.
Season with salt and pepper when the meat begins to tenderize.
Once cooked, strain the gravy and thicken it with 1 tablespoon of flour until brown.
Pour some gravy over the meat and serve the rest in a tureen.
Garnish the dish with fried potato olives.

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 meat that becomes tender through slow, moist braising.
- Bacon
- Adds fat and savoury flavour that seasons the meat and vegetables as it cooks.
- Onions
- Soften and sweeten during stewing, adding depth to the juices and gravy.
- Carrots
- Release natural sweetness into the braising liquid, rounding out the gravy.
- Flour
- Thickens the strained gravy so it coats the meat and serving spoon.
The step that matters
Season with salt and pepper when the meat begins to tenderize. Salt added too early can draw moisture out of the meat before it tenderizes, while adding it at the right point lets it season the meat and juices evenly. Timing matters because the meat's surface and juices change as it cooks.
