Of the 4 Indian manufacturers - and I include Pataks here because I've met them and eaten with them and I know they're not blacked up Yorkies - three of them list chillies as an ingredient in their masalas, whereas only Pataks don't, and they merely list 'spices' in the relevant place, so quite probably including them.
I think that if I were suddenly to develop an allergy to the noble fruit, I'd have to be extremely careful around any form of curry. Which would be a bugger, because I like curries, and I like also Thai food, and even some Chinese dishes have chillies in them.
No Malaysian, either.
Pretty please, tell me allergies aren't infectious.
