string and break up beans the day before, then place in a large cooker with lid to refrigerate overnight.
Be thorough in stringing beans because the strings will never become tender during cooking. Also, if the bean pod is spotted or discolored, open it up and put the little beans in the pot rather than discarding the whole bean!
The next day remove beans from refrigerator and cover about half-way up with water.
Add bacon grease, salt pork, ham and salt. Cook on medium heat, with lid slightly ajar to allow steam to escape, for about 5 hours.
The beans should boil gently. Stir about every 15 minutes, while you do other tasks nearby.
The idea is to boil away most of the liquid before enjoying the beans, so if they still have a profuse amount of water after 4 hours, remove lid to allow more liquid to evaporate, Serve and enjoy!
