They were very tasty. Not tandoori but lovely Indian spiced flavour. I cooked under the grill as we're experiencing awful weather again (still), but these would be brilliant on the BBQ. I just put all of the marinade ingredients in the bullet blender and turned it into a paste, rather than grating and chopping. I added a tsp of indian green sandwich relish / chutney which is mainly coriander, and 2 tbsp of yoghurt. Everything else was as shown in the YouTube video.
Next time I'll consider using mint jelly in the marinating or at least with serving.
