Sorry 976bar ... I didn't mention I would like to know how to cook the lamb tikka so that it's not chewy or was yours chewy 
Thanks in advance for any info !
Hi Colin,
Keep the lamb chunks big (about 3 inches), ensure you marinade for 48 hours, this will tenderise the meat, put in a roasting dish, cover with foil and bake on 150 degrees for 20 minutes, then remove, put on skewers and finish off on the BBQ for that smokey flavour.
Mine was not at all tough or chewy at all, just succulent lamb with a bit of bite
