OK, so I'm a new convert to parchment paper. I use it almost any time I turn on my oven. And I'm also a cheapskate. So after discarding after first use, I've started reusing the parchment I use to bake cookies (my guy eats a LOT of cookies and I bake them one batch at a time).
I'm not so much a cheapskate that I would save the parchment I used to roast veggies for the next time...
Do you re-use? If so, how do you decide that the time's ripe for new paper? If not, wanna share experiences that would make me reconsider my re-use habits?
