I love chickpeas but have only used canned ones. I've made a stew with Kabocha squash, red lentils and chickpeas. And other things. It's done and there's something I don't like about the texture of the beans. They're done but just have a rough/grainy/something-ness to them. Do you think they're old? I got them in bulk from our local co-op. Any ideas? I may make this again but will go back to the canned beans. TIA.
