Thank you very much. I will go ahead with corn oil. How nice of you to offer assistance in canning! But wait a minute. I think I missed those links posted in this thread regarding canning. Let me read this thread completely and I will get back to you if I have any doubt in canning procedure. I thought I was ready to make the chutney, but just realised that I don't have cayenne. I have crushed red peppers, red chilli powder(not paprika), kashmiri chilli powder, fresh thai green chillies. Any of these can be substituted for cayenne? Also, I wonder why we should use canned tomato paste in this recipe? I was under the impression that canned foods, once opened and cooked, should be finished as soon as possible? So in this case, we open the canned tomatoes, cook it, again can it and keep it for long time? As a lot of you tried this recipe already, I hope no hazards in doing that!
