When I’m baking cookies on parchment paper, which side of the paper should I use? And can it be used more than once? —D.P., Willowick, OhioParchment paper is a heavy paper that’s resistant to grease and moisture. It’s excellent for lining baking sheets when making cookies, because it makes cleanup a snap. There is no right or wrong side to parchment paper, so either side can be used. For the best baking results, use a fresh sheet of parchment paper for each pan of cookies.
