Sure, y ou fridged up those leftovers with the best of intentions but days later they still languish. Then it's weeks and now they're so deteriorated that you can finally toss them with a clear(ish) conscience. The progression parallels certain aspects of personal relationships but this is not the forum for that. This week, Nancy Leson and I discuss, with only a little self-congratulation, how much better we've become at using up leftovers now that our supermarket visits are so infrequent.
