Nope, I can't eat any offal meat what so ever, and yes, it was served to me when young, and I would heave. It just wouldn't go down my throat, and I didn't know what it was being served to me...liver looks like steak, which I love, and my mum use to cook it with onions and couldn't understand why I would'nt eat it, but as good as it looked, I could not physically swallow it, no matter how hard I tried. It use to make me want to vomit, I would heave, and I never new what it was.
I was being serious about the grapefruit thing, I have heard, but can't recall where or why I even went there, but that humans are divided scientifically with this grapefruit taste. I think I read it in a magazine a few years back. Not sure if it has anything to do with offal meat, but most certainly I read that humans either taste grapefruit as bitter or sweet and that scientifically, it is one way human are divided from the others, which I found very interesting.
My grandmother was brought up of offal meat and always said she couldn't eat it, and when she made kidney soup, she would strain out the kidney but would keep the flavour. I could eat the kidney soup when it was just soup with no kidney, but if I got a fleck of that flesh, nope it would make me heave. I couldn't physically swallow it, no matter how hard I tried, which I did because I couldn't get sweets unless I did, and nope still couldn't swallow it.
The only way I can think of the way it is for those who can't eat offal meat, is that if you had smelt bad meat, milk, or a bad egg, that is what I taste and smell. It is horrid to me, and it has been as a very little one, when I did not know what it was.
This makes me curious how many people like offal meat, that like grapefruit?....I gather many, because the study I read never mentioned offal meat.
Netherless, I find it interesting that the taste of grapefruit would be such that it has been given or proven that clearly that half the people taste it one way and the other another.
