Now, I don't use beans nearly as often as I should, since dh isn't a big fan of them. But I do love them, especially in soups, and use them more in the winter. I've always soaked dry beans rather than used canned beans, and never had trouble with them. But since starting to add vinegar or whey as per NT, I've found that when I cook them, they don't soften properly. I know that happens when you cook or soak beans with salt, although I've found (in the past, prior to soaking with acid) that the salt in my homemade stock doesn't seem to have as much of an effect as it's reputed. So why are my beans, soaked with whey or vinegar then cooked in water, not softening??? I'm considering that my beans might be old. But I didn't buy them all that long ago, and it's been a couple different kinds of beans now.
