Instructions

  1. Tie roast if necessary.
  2. Combine lamb with the next eight ingredients. I use a large ziplock bag for this.
  3. Marinate at least 1/2 hour, or overnight.
  4. Take roast from marinade.
  5. Heat marinade in a saucepan with the peanut butter and water until thick and bubbly to make the glaze.
  6. Roast meat at 170C for 1 to 1 1/2 hours, until cooked to your liking, brushing with glaze during last 10 minutes.
