Parchment paper for the dutch oven. Makes clean up a snap. Ive been making my own liners for a couple years now, its something like this. I buy the longest parchment paper I can find, then I just fold diagonally till the triangle goes from 0-1" then trim to make the biggest circle I can. A little practice and you will figure it out.
