I love coriander, but your post has prompted me to Google about your dislike. You can even join a coriander hating website. Lol.

Personally I hate anything with almond paste in such as marzipan, Bakewell tarts etc, yet I can eat almonds in chocolate bars or from the nut selection at Xmas. Even the smell of almond scented shampoo leaves me heaving.
You may just have an inbuilt response to a trace element in the coriander plant.
