Prepping ahead is perfect during the holiday season, for intimate dinners, or even to get a jump start on Sunday Dinner. Trim the meat and remove the silver skin, then store in an airtight container or sip bag in the fridge for up to 3 days. If you need it to last longer, wrap in a layer of plastic wrap, then add a layer of tinfoil and freeze it for up to 3 months. Thaw completely before cooking.
