The Indian store on Robie now has bags of whole Kashmiri chillies.
Here is a link to the Rogan Josh recipe I wanted these for - in case anyone is interested:
My curry still didn't get as red as his. I think maybe because I didn't quite grind it into a fine enough powder. I either use goat meat (Indian store on Robie - $7.99/lb) or lamb from the grocery store to make this recipe.
Try the Big Ray Asian Store in Dartmouth. They have some Indian spices and ingredients - not extensive mind you - but I'm always surprised what I find there. The lady owner is very helpful and if she can find a supplier she'll bring it in.
"You can find this spice in any Indian grocery store and it may be sold under the following names: Kashmiri chili powder, Kashmiri mirch, degi mirch, deggi mirch, deghi mirch and similar variants."
Did you ask for any of these names on Robie Street?
Good luck in your pursuit.
