My wife and I recently tried cooking frozen green beans by boiling them on the stove. They tasted fine, but the skin of the green beans was really, really "squeaky" on my teeth. My wife didn't really understand what I was talking about, but it drove me crazy. It's like nails on a chalkboard to me.
My wife really likes green beans, and I've never minded the soggy canned stuff, but I really do not want to eat any more like this. Is there some secret to cooking them that can make them less squeaky or this just an inherent part of green beans?
