I love PB. I buy the natural stuff (no added sugar, just peanuts and maybe a smidge of salt), but I'll eat Jif in a pinch. Nothing TOO sweet or oily. Any texture is fine, though I have an affinity for that rough-ground stuff that I realize most people don't share.
Jelly (jam), I like strawberry or mixed berry or apple butter. I usually pass on PB&J, though, especially if the person making it uses too much jelly or thinks that grape is remotely OK. It is not OK, not unless you have no tastebuds.
I use peanut sauce a lot in stir fries, or for dipping steamed vegetables. And make PB cookies for special occasions.
