I hate plastic tupperware and I'm always looking for a good alternative. While I am pretty happy with my glass tupperware I have now, I have to admit this enamelware is pretty amazing. I'm pretty sure I can find a good excuse to pick some up. While it can't be used to heat up food in the microwave (enamel is basically a ceramic layer over metal) you can put it directly on the stove top to reheat food. The $49 price tag is a little steep, but this is one of those things that is going to literally last a lifetime.
