@Red Leg my post was not directed at you, in fact I started para two as I did because I was not accusing you or including you in those who would not eating or try a food before you developed a like or dislike on its taste. I do not know you so cannot and would not specifically say you were one way or the other. I was speaking broadly across my trade as I did (before retirement) experience this behavior most often.Who said anything about not liking anything I haven't tried - or virginity for that matter?
I obviously wasn't clear. I have tried foods all over the world - I haven't counted the countries but I am sure it is at least 55. Many of them were wonderful, others were charitably edible, and yet others were disgusting. There are people in your trade who are artists and others who should be brick layers rather than cooks or chefs.
I have had Haggis several times and could not abide it. Like all food questions, it is an issue of taste - literally and figuratively. The fact that you have never found anything you couldn't or wouldn't eat again is irrelevant with respect to those things another would just as soon not be required to taste again. Being handed a goats eyeball at an Arab feast as we sat around a mound of rice with a goat carcass draped across it is another experience I can pass up in the future - though kabsa itself (fowl, goat, camel, or sheep) and the Bedouin eating tradition are something I enjoy.
I think we can find complete agreement in having little patience with those who refuse to try something at all.
I also agree with your statement that some cooks/chefs should not be in the trade, that is the same in all trades, some brick layers should not be that either. To be in my trade to be good one must have passion, work ethics and thick skin to name a few. Not all have and demonstrate those requirements.
My post was directed at those who we both agree on in your last sentence. Will not or have not tried the item but have a voiced opinion on its taste.
