Quarter of Lamb Roasted

Ingredients

1 quarter of lamb
coarse sea salt
black pepper
butter

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 quarter of lamb with coarse sea salt and black pepper.
Place the lamb in a roasting pan and dot with butter.

Roast

Roast in the oven for about 1.5 to 2 hours, basting occasionally.
Ensure the internal temperature reaches at least 145°F (63°C) for safety.

What each ingredient does

Lamb: Provides the main protein, whose muscle fibres firm and set as the meat cooks through.
Butter: Adds fat that carries flavour and helps keep the surface moist and lightly browned.

The step that matters

Ensure the internal temperature reaches at least 145°F (63°C). A quarter of lamb varies in thickness, so roasting time alone can leave it underdone at the centre or overdone at the edges. Checking the internal temperature with a thermometer shows when the thickest part has reached a safe, evenly cooked doneness.
