This is a funny thread. So many strong feelings. For me I think the scallop thing was that originally I just didn't like them. But when I was a kid one night for dinner my mom made them and was so excited, she thought I loved them for some reason. Me, not wanting to disappoint choked them down and then a few hours later it was like bubblybarrister with the yams.
Years ago I had barbecue spare ribs and homemade brownies and then the next day I got the norovirus and for years I associated the taste of those foods with the nausea I experienced but I got used to them again eventually.
I'm surprised that so many people hate salmon specifically. I always thought its flavor was a little too mild.
