Thighs or drumsticks are the best meats for this simple tandoori dish, though this is a great marinade for any meats or fish that you can then roast, grill/broil or barbecue. The yogurt and lemon go a long way in helping to tenderise the meat and almost break down the structure so that the spices can better penetrate. Use mild paprika powder to give a good flavour and colour. In India they use chilli powder, which makes this dish seriously hot.
