Ingredients

  • 2 tbsp medium-hot mustard
  • 7 tbsp butter, cut into cubes
  • 2 cloves garlic, chopped
  • 3 tbsp pink peppercorns, crushed
  • 1 tbsp coarse sea salt
  • 4 tbsp breadcrumbs
  • 2 racks lamb
  • 2 tbsp olive oil
  • 1 2/3 lb small new potatoes, halved lengthwise
  • 3/4 cup thyme leaves, chopped, reserving a few sprigs to garnish
  • 2/3 cup dry white wine

Method

  • Preheat the oven to 400°F. Mix the mustard, 3 1/2 tbsp butter, garlic, pink peppercorns, salt and breadcrumbs. Press into the lamb to form a crust then roast for 15-20 mins. Remove from the oven, cover with foil and set aside to rest.
  • Meanwhile, heat the oil in a large frying pan, add the potatoes and saute for 20-25 mins until tender. A few minutes before the potatoes are done, add the chopped thyme leaves. Season.
  • Deglaze the roasting pan with white wine, scraping any browned bits then pour into a saucepan. Bring to a boil, remove from the heat, then stir in the remaining butter. Serve with the meat and potatoes. Garnish with the thyme sprigs.
