Yes, you need to drain them, and the closer the expiration date, the longer they need to drain. Either cut them in half or into 3-4 slices (depending on how big you want your final pieces), and let them drain on a few layers f paper towels for at least 4 hours. If they are really wet inside, you more paper towels or change them, and let the slices Darin for 6-8 hours. Tear them into pieces when you are ready to use them.
