To Roast a Leg of Mutton
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 400°F (200°C).
Roast and serve
Place the leg of mutton in the oven and roast for about two hours.
Baste the meat regularly to keep it moist.
Serve with onion or currant jelly sauce.

What each ingredient does
- Leg of mutton
- Is the main cut of meat that is roasted and served as the centerpiece of the dish.
- Onion or currant jelly sauce
- Is the accompanying sauce served alongside the roasted mutton.
The step that matters
Basting the meat regularly. Basting spreads melted fat and juices over the surface during roasting, which helps keep the outer layer from drying out. Because the leg is large and the roasting time is long, skipping basting risks a dry exterior.
