Indian tandoori marinade recipe

hey say tandoori chicken was invented by a shrewd Indian restaurateur who couldn't see tandoors (bread ovens) stay idle when there was no naan to bake. Knowing Indian business acumen, it sounds a plausible theory.

But back to gastronomy. Here is my recipe for the incomparable tandoori marinade for barbeque.

1. Peel one onion, half a head of garlic and about 6 cm of ginger. Put them in a kitchen processor and reduce them into homogeneous pulp. Add some water if necessary.
2. Chop finely one or two seeded chilli peppers.
   
3. Put about 150 g of natural yoghurt (the fatter the better, never skimmed one!) into a big bowl.
4. Add 1, 2, Tandoori Spice Mix, palm sugar and fish sauce.
5. Stir well until everything dissolves. It should taste pleasantly pungent with a nice balance of sweet, sour, salty and spicy.
6. Chop chicken, fish or what have you into bite-size chunks and mix well with 5.
7. Cover with cling film and let stay overnight in the fridge. Stir every 6-8 hours.
8. Remove from the fridge a couple of hours before cooking. It helps to have your barbecue evenly cooked when the raw mix is of room temperature.
