Yes, you can. I would suggest you divide the dough into balls and then place a moist paper towel on them and store them in an airtight container to retain the moisture. It stays well for 1-2 days. Let it come to room temperature and then knead it again with a wet palm before making rotis. To freeze - place parchment paper between each (uncooked) rolled-out roti in order to prevent them from sticking. Then place them in a ziplock bag. Leftover cooked rotis can be stored in the fridge for 1-2 days. Reheat and serve. They will harden though. These gluten-free rice flatbreads taste best when served fresh.
