I use up spaghetti within days or weeks of buying it, because my preferred pasta shape is spaghetti (pasta shape preference might be another topic, but I digress...). Anyway, I was wondering about the shelf life of boxed pasta. It just seems like it shouldn't go bad, but there could be a reason to toss it that I don't know about. I also realize that it's a cheap item that can be replaced easily, but I'm curious. I've got a few boxes that I've had for over a year now. How long do you hang onto a half-used box of pasta before you toss it?
