Roast Loin of Mutton

Ingredients

5 lbs loin of mutton
salt
pepper

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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

Preheat the oven to 350°F (175°C).
Season the loin of mutton with salt and pepper.
Place the mutton in a roasting pan.

Roast and rest

Roast in the oven for about 1.5 to 2 hours, or until the internal temperature reaches 145°F (63°C).
Let it rest for 10-15 minutes before carving.

What each ingredient does

Loin of mutton: Is the main cut of meat, providing the flavor and substance of the dish.

The step that matters

Roast until the internal temperature reaches 145°F (63°C). Mutton loin is lean and can turn dry and tough if overcooked. Checking the internal temperature shows when the meat is done rather than relying on time alone. Resting it afterward lets the juices settle before carving.
