DH and I have been invited to a curry night by someone we don't know that well. I have a serious nut allergy and over the years I have decided to play safe and usually take my own food. A little over the top most people find. Anyway I replied to say yes we would love to come but please could I bring my own food. The host is very put out and I feel I have upset her. I havent cooked a curry before and when I look into buying spices etc I came across an article recently saying that there have been reports of spices being substituted with nuts which is worrying me. I was on planning on taking a dish of chilli instead. Am I being unreasonable?
