We still use the cast-iron ware that was my great grandparent’s, and it still works great.   There is no better “non-stick cookware” to be found.

Here’s a little trick that I picked up one day at Waffle House:   if you crumple up a piece of aluminum foil, it makes a great scratcher with which to clean a pot or skillet (without soap).   Then, just throw it away.
