--------  ------------  --------------------------------
   6      tablespoons   coriander seeds
   4      tablespoons   cumin seeds
   7                    dried chiles
     3/4  tablespoon    whole black peppercorns
     3/4  tablespoon    black mustard seeds
   2      tablespoons   ground turmeric
   2      tablespoons   ground fenugreek

Preparation:

Preheat the oven to 300 degrees. Line a baking pan with foil and place the whole spices in separate heaps upon it (this is done so that you can remove the smaller spices as they are ready). Place the pan on the top shelf of the oven until the spices become aromatic and are slightly browned. Do not over-roast them. Place the roasted spices (in several batches) into the spice grinder, a blender or a mortar; grind or pound to a fine powder. Accumulate them in a storage jar. Add the pre-ground turmeric and fenugreek; cap the jar and shake until the spices are well mixed.
