Instructions

  1. Using a food processor (if you have one), finely chop the onion, apple, celery and garlic.
  2. Melt the butter in a skillet and cook the vegetables until softened but not browned.
  3. Stir in the curry powder and thyme; cook, stirring, for 1 minute.
  4. Stir in the chicken stock and tomatoes; simmer for two minutes.
  5. Season with salt and pepper; add more curry powder if desired.
  6. For a smooth sauce, puree in the food processor and pour back into the skillet.
  7. Add the lamb to the skillet; cover and simmer until the lamb is heated through, about 10 minutes, adding a little more stock if the sauce is too thick.
  8. Serve over rice.
