Flours, nuts, and spices more than two years old: First of all, good on you for keeping these ingredients fresh in the freezer in the first place! That said, if you haven't cooked with them by now, it ain't ever gonna happen. I bought five pounds of cornmeal and grits at a mill over two years ago, and they're still in the freezer. They haven't gone bad; they're just taking up space. I'm giving myself two weeks to use them or toss them.
