Ingredients

Directions

The book says “a brisk oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Season the lamb with pepper and coarse sea salt.

  2. Spread thickly with butter and dredge with flour.

  3. If the meat is not fatty, lay thin pieces of pickled pork over it.

Roast

  1. Cook in a 400°F (200°C) oven for 30 minutes.

  2. Add ½ cup of water and baste often.

  3. Cook for a total of 2 hours for well-done meat.

Serve

  1. Serve with mint sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lamb
Is the main cut; slow roasting in its own juices keeps the meat tender and moist.
Butter
Adds fat that coats the surface, helping it brown and carrying flavour into the meat.
Flour
Dusted over the buttered surface, it helps form a browned, slightly crisp crust.
Pickled pork
Thin slices laid over lean meat add fat and salty flavour as they render during roasting.

The step that matters

Cook for a total of 2 hours for well-done meat. Lamb roasted too briefly stays pink and tough inside, while overcooking dries it out. Basting with the water helps keep the surface from scorching and the meat moist over the long roast.
