There are certain foods from my childhood that I remember in a less than favorable light. As such, I have avoided the like the plague since.
Then at dinner at a friends house, Brussels sprouts were served. To be polite I put a couple on my plate. They were pretty good. I went back for seconds.
Recently, while making DW a liverwurst sandwich I tied a bit "just to see if it was as bad as I remember." It wasn't. It wasn't great, but it wasn't that bad either.
O.K., Spam is still just as bad I remember.
So, what have you thought you hated, but due to changing taste, better preparation, or something else, now say,"Hey, that wasn't so bad."?
