TIP: Whole Kashmiri chilies can be identified by their wrinkly texture and bright red colour. If you are going to make your own Kasmiri chilie powder from whole, it's worth mentioning that you should de-seed the chilies before grinding. You can always tell when a chili powder has been ground from whole chilies because it is orange in colour (red 'the shell' and white 'the seeds', = orange). The significance of Kashmiri chili powder is that it gives a suitable heat and a deep red colour (which is obviously great for cooking), hence grinding whole Kasmiri chilies defeats the object of their significance.
To remove the seed, simply put them 'whole' into a blender/food processor for a brief moment (1-2 seconds), this with split the shell. Then pour the partially broken chilies onto some brown paper on the floor and pick out the red shells, them discard the white/light brown seeds, and THEN blend the shell only, time consuming but worth it if you can't get hold of the powder locally. Bingo!
