Huh, that's funny. I
love the flavor and texture of parm from a brick. I am usually far too lazy to grate my own though, and do use the pre-grated stuff often. But on the occasion where I do grate my own, or am in a restaurant where it's done for me, I resolve to grate it myself more often.
This is all just a matter of taste, though. Sounds like maybe you grew up with the green tube mystery powder, and developed a liking for it, and that's "parm" for you. You never developed a taste for the "real" stuff, and that's fine! We all like what we like, and no one should tell us that we're liking it wrong. (I, too, grew up with the green tube mystery powder, but my tastes changed. It happens.)
> Sometimes if I'm looking for a snack I just pour the green tube mystery powder directly into my mouth.
This made me chuckle; I used to do the same thing when I was a kid (despite the disapproving look from my mother). I've tried it as an adult though, and now I don't like it (not quite "gross", but not something I enjoy).
