The foods most people dislike are usually those I will choose ... squid, liver, blue cheese, black pudding.
There are very few things I cannot eat. Celery is one but only if its raw as the smell makes me nauseous. Cooked celery in a mirepoix is fine. I cannot for the love of all that is holy get coffee down my neck. No one is likely to serve them up to me but pigs trotters are a serious no go. But that seriously is about it. Oh tripe. I could if I had to but I would struggle.
There are things I prefer not to eat but if i came round for dinner and they were on my plate I would eat them ... baked beans, tinned tuna, pickled onions.
When I was little you had to eat what you were given. Its left me with the ability to get most things down my neck without puking.
About the only thing I don't like is tripe. As a Southerner I don't get subjected to it much as I think it's more of a Northern dish, but as I go to Yorkshire most weekends, needless to say trying tripe was part of an 'initiation ceremony.' I think an eraser would be less chewy.
Tripe would be a no no for me but I am unlikely ever to be offered it! Same with black pudding.
Of the more normal, everyday stuff I loathe cucumber, fresh coriander (YES, soap exactly - thought it was just me!!) but the seeds/ground stuff are fine, rocket (I know it's trendy but bleeaarrgghh!). I adore the smell of cinnamon, and loved Dentine gum, but cook it in an apple pie or something and it makes me puke!
I love offal (liver not so much but I can eat it), fish, meat, vegetables, fruit, cheese (the smellier the better - oh, but not goat's) ...........other than the above, if it is edible I will eat it. Providing it is gluten free!
