Roast Haunch 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. 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

  1. Preheat your oven to 400°F (200°C).

  2. Season the haunch of mutton generously with coarse sea salt and black pepper.

  3. Rub fresh herbs and butter or oil over the meat.

Roast and rest

  1. Place the mutton in a roasting pan and roast for about 1.5 to 2 hours, basting occasionally.

  2. Check for doneness; the internal temperature should reach 145°F (63°C) for medium-rare.

  3. Let the meat rest for 15 minutes before carving.

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

What each ingredient does

Mutton
Provides the main meat, which becomes tender and juicy as its connective tissue breaks down during roasting.
Butter or oil
Carries heat across the surface and adds moisture and fat, helping the outside brown.
Fresh herbs
Add aroma to the surface of the meat as it roasts.

The step that matters

Check for doneness. Meat keeps cooking as it sits, and the internal temperature is the reliable guide to doneness, not the clock. Checking with a thermometer helps avoid overcooking the lean meat.

Swap the rosemary

How well each one fits the dish's main ingredients (mutton, pepper, thyme, butter):

  1. Parsleyfits better
  2. Marjoramfits better
  3. Sagefits about as well
  4. Rosemarythe original

Fit is the average pairing score against mutton, pepper, thyme, butter. Candidates are from the same food group and used in at least 100 recipes.
