I can lots of beans - kidney, pinto, black, october, chick peas, canellini. I like them for the convenience....and they taste much better than commercial canned. Although I'm home all day, it still suits me best to open a jar or two at times rather than soak, etc.
DH & I also like chick peas and black beans on salads. The texture of a canned bean suits that purpose best to us.
Regarding cost....depending on the price of dry beans, I can do them for around 30 - 35 per pint. Canellinis run about 55- 60 per pint because the dry beans cost more than most, at least around here.
That doesn't count the cost of canning jars....but you'll reuse the jars over & over. I have jars I've canned in for 25 yrs. Their cost has been spread out over so many jars of foods that it doesn't matter anymore.
I use the BBB directions - soaking, and then cooking for 30 minutes before processing. I just hold them at a very low boil (barely) for the 30 minutes. They come out great...all varieties. Not mushy.
And BTW, I've tried the first method - putting beans in a jar, covering with hot water, and immediately processing them. It's not as nice a product. The outer skin on the beans stays harder, and they turn thick in the jar. Some crack open and almost "burst". Edible....but not nearly as nice.
