OT: What to do with old beans
Hi,
I have done this with old chick peas and old black beans, and canning the beans really works. Other than transforming old hard beans into perfectly good beans this method has the added benefit of leaving you with beans that are instantly available for quick meals, all you have to do is open the jar, no soaking.
This method was not my idea, I found it at Back Woods Home, I have cut and pasted the reference for you.
Regards,
Kevin.
"Old dried beans
I’ve had pretty good luck with those old beans by soaking them in boiling water overnight (pour boiling water on the dry beans, then let sit overnight in a cool place), then rinsing, using fresh water, boiling them for an hour, and packing them into canning jars to within an inch of the top, pouring the water on to within an inch of the top, adding ½ tsp. salt to pints, 1 tsp. to quarts, then pressure canning them at 10 pounds pressure for 75 minutes for pints or 90 minutes for quarts. (If you live at an altitude above 1,000 feet, consult your canning manual for directions on adjusting your pressure to suit your altitude, if necessary.)
The pre-soaking, boiling, and pressure canning seems to help a great deal. If they still seem tough, pulse through a blender before you use them to make kind of a bean mash; it’s good in most recipes calling for pintos, including refried beans.
Another way to use them is to make bean flour out of them. Run them through your flour mill or meat grinder to chop them fine, then whiz them in your blender to make bean flour. You can use this in a variety of recipes. It thickens gravies and makes dandy refried beans when you add boiling water and simmer with spices in a pot on the back of the wood stove or in the oven. I’m sure a slow cooker would work too.
