This morning I learned that I am not the only one lucky enough to have a couple of these - aluminum one-pint sauce pans. Mine of almost 100 years old. They've been through three generations. I have burned a few things in them - including water - and they clean up beautifully. Their benefit is heating one-serving foods. Water for tea; soup for one; a reheated leftover.
So far as I know, one-pint sauce pans are no longer made. If anyone knows a company that makes them, please tell me. Some days I need a third or fourth when the first two of in the dishwasher.
