I cannot and will not eat ANYTHING with coconut in. Which counts out a lot of curries. Even the smell of coconut makes me gag - I gag when a person who has washed their hair in coconut shampoo walks past. I have vomited when someone has eaten a Bounty bar in the same room as me in the past.
I can't help it, but there is no way on earth I would attempt to go round someone's for a meal if I was told that curry would be served. I would politely decline the invitation, and if I had already accepted, then I would explain myself to them, but get myself out of the invitation easily.
I know myself that it is easy to cook a curry without using any coconut products, but most people don't.
I wouldn't take the risk. I would vomit if I tried to eat ANYTHING containing coconut, no matter how much I wanted to eat it to be polite.
I'm generally the most unfussy person I know, and will try anything once. But if it has coconut in, then I can't. I have vomited after just one small nibble of a homemade biscuit that I hadn't been told contained dessicated coconut.
Doesn't help that I ALSO have a lot of allergies though...can't eat kidney beans, or drink Red Wine or tea (am allergic to tannins), and am also allergic to certain preservatives that are often found in jarred sauces, at home I always make my own, rather than take a risk of anaphylaxis, so I have to check VERY carefully what is being prepared before I eat anywhere.
It's not been an issue for a while though - it is seemingly impossibly for anyone else to cater for the multiple allergies in my family. Despite the fact that I have to on a daily basis.
I have the food allergies mentioned above, DD is allergic to kiwi, pineapple and papaya, DS1 is coeliac, DS2 is also allergic to kiwi, pineapple and papaya, and also to bananas, due to the natural latex in them, and DS3 is severely allergic to Dairy, Soy and Nuts.
I don't bother accepting invites to friends houses for dinner now, I would have to cook an entire meal to take with me, and I might as well do that at home. I am now the default host. And my friends are always impressed with how nice-tasting the food is considering the restrictions placed on my ingredients!
