I am something of a foodie and, an adventurous eater but, everything must be prepared and cooked properly and, believe me, I can taste it if it has not been done properly.
An example: I like teriyaki chicken and, last evening, we dined at a Golden Corral restaurant. They had teriyaki chicken on the buffet and, of course I took a helping for myself. One taste however and I knew the had marinated the meat then, left the marinade at room temperature for an hour of more before cooking it into the sauce that was coating the chicken. While it's normal and, proper to make the marinade into the sauce, you can't leave it out that long after removing the meat. the blood and other juices form the raw meat that are now in the marinate turn, go bad and, even though cooking does kill any harmful bacteria, the off flavor remains and, that is not good teriyaki.
I informed the staff of the problem and, was soon given a fresh helping of teriyaki chicken that did not have the off flavor so, Golden Corral did well and, did the right thing but, the mistake never should have happened to begin with.
I will eat almost anything so long as it is prepared properly and, yes I have tried Fugu, it's quite good if you enjoy sushi and other raw dishes, but quite risky if not prepared properly. mine was thankfully and, I would eat it again if I get the opportunity to dine with a Fugu master to prepare it for me. I'd never attempt it myself, one wrong move, a small nick with the tip of the knife and, I'd be feeling like I dropped a few hits of acid in short order, a big wrong move and I might finish the meal dead.
