Leg of Lamb, Roasted

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 and cook

  1. Soak the leg of lamb in warm water for more than 2 hours.

  2. Wrap the lamb in a cloth and boil it slowly for 3 hours.

  3. Cover the lamb with buttered paper and roast it at 400°F (200°C).

  4. Baste the lamb frequently to prevent burning.

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

Leg of lamb
Forms the main body of the dish, and its meat becomes tender with long, slow cooking.
Flour
Listed in the ingredients but not used in any step, so its role is not stated.
Buttered paper
Covers the lamb during roasting, helping to hold in moisture while the meat cooks.

The step that matters

Basting the lamb frequently. Basting spreads fat and juices over the surface, which keeps the meat moist and helps prevent the exterior from drying out or burning during roasting.

Swap the mint

How well each one fits the dish's main ingredients (lamb, flour, pepper, sauce):

  1. Parsleyfits better
  2. Turmericfits better
  3. Capersfits better
  4. Mintthe original

Fit is the average pairing score against lamb, flour, pepper, sauce. Candidates are from the same food group and used in at least 100 recipes.
