Parchment Paper

Rolls of parchment paper (available in most grocery stores) are difficult to manipulate because they always seem to return to their rolled shape. That is why I recommend flat sheets of parchment paper, which are available online in both half and full sheet pan sizes, plain or non-stick.  Parchment sheets are great for both cooking (lining pans), and storage (wrapping a sandwich).  Personally, I don't think aluminum foil should ever touch food, so I also like to line my foil with parchment.
