As a further elaboration: growing up, I absolutely hated pasta salad. I could not and would not eat it. But one day, when I was about 22-23, I was working somewhere that includes meals, since shifts were literally all day for a week (save eight hours for sleeping). The cook made a pasta salad that I could only describe as “orgasmic.” I ate that same pasta salad for every meal for the next two days until they finally tossed the leftovers. Ever since then, I have been “converted” to enjoy pasta salad. That one dish completely changed how my body reacts to a food that I already tried several times.
For me it was fish. When I grew up we didn’t eat out often and when we did I never had fish. The fish my mom cooked at home was few and far between and it wasn’t very good in my opinion.
Up through college I would have said I didn’t like fish, but when I started working I went out some work dinners where the company was paying for it at upscale restaurants. The first few times I ordered steak, but I got old so I decided to try the fish dish. I still remember it, 30 years later, that I had a fish with nuts on top that was just awesome. After that when I went into fancier restaurants I tried to find a fish as good as that. And the fish weren’t good, but some of the fish were awesome, and I really found I liked fish if it was prepared right.
