CONTEXT: Beans freeze marvelously. I put mine in freezer bags and lay them flat so they freeze quickly and are easier to thaw.They are very sturdy little nuggets of joy and hold up well to canning or freezing without getting mushy.Different beans behave differently. Pintos soften quickly and don't have much of a skin. Black beans keep their shape and skin a lot longer. Kidney beans are in the middle- if you boil them too long they will mash but they are a lot sturdier than pintos.  <sep>  Q: Can you preserve canned kidney beans so that they still have their shape? A: They are very sturdy little nuggets of joy and hold up well to canning or freezing 
How long will they be preserved using this method?
