I don't use parchment paper much at all. After recently learning that wax paper does not replace parchment, I was also told that parchment can be reused. UGH - really? I think perhaps, only for very limited things - like just used it last night to roast some squash with oil and rosemary. I looked at the paper after, and into the garbage it immediately went. And what's with the pan getting all greasy anyway???
