I'm freezing snicker doodle dough but I realized I don't have any saran wrap! I have wax paper, parchment paper, press and seal wrap (I'm not sure if its safe to wrap cookie dough in it), ziploc freezer bags, and aluminum foil.
What is DT? If I knew that I might be able to help you If you are speaking of a type of sandpaper, then it could be mineral (emery) clothThey come in micro grit and macro grit.
Use anything airtightI'd probably go for the ziplock freezer bagYou could also use a plastic or glass container with an airtight lid but those are kind of bulky in the freezer.
