Combine 4 to 6 tablespoons of any natural yoghurt, the equivalent of 6 cloves of garlic in any form, one heaping teaspoon of Kashmir chilli powder (optional), four heaping teaspoons of sweet paprika powder (not smoked) as an alternative, two heaping teaspoons of cumin powder, the juice of a whole lemon, 2 teaspoons of salt, and 1 heaping teaspoon of green cardamom powder (or substitute with coriander powder or garam masala if that's what you have). Mix well to form a marinade.
