The bag is a crock pot liner. You can find them in the spice/baking isle or the aluminum foil etc/ Ziploc bag area of your grocery store. They are great for easy clean up, especially your crockpot. You can substitute a chuck roast if the cachete ( cheek meat) is not available. Ask your meat market butcher. Don't get a molcachete from China, get one made from volcanic rock from Mexico. Look on Google on how to season and prepare it before use. You can even use a spice grinder.
