Absolutely! Place can in a crock pot (a smaller crock pot works great but any size will do). Cover can with hot tap water in the slow cooker until the water is two inches above the top of the can (you can lay the can on its side. Set slow cooker for 8 hours on low. Remove can from crock pot using tongs. Allow the can to cool completely before opening. You can put the can into some cold water to speed up the process.
