I have an old Guardian turkey roaster. I have used it for years. It's huge and wide so I use it to make stews or other large meals big enough to feed an army.

I used to do my turkeys in it but last year I brined my turkey and used a v rack. It came out better than using a roaster. I still use the roaster for epic amounts of pot roast.

I also have a SilverSeal chicken roaster I use like a dutch oven.

They're' neat old pans.

If I had a vintage roaster I would have the perfect dutch oven. I find that they are all too heavy for me to handle once the food is in -- think le creuset or even cast iron. My Mother also had guardian pots and pans. She also had a big roaster, probably aluminum, that she used on the stove top. Naturally, for a family of six it was not too big. Anyway, where can I get a heavy enough pot that wont be too heavy?

I did find an excellent one on Ebay. It's a LISK roaster. The top dips in the middle so the condensation makes the turkey really moist. That was my first turkey to bake ever, and it turned out excellent. I also bought another smaller one at a thrift store. It is one of the older blue enameled roasters that has a lid that dips in the middle. So far, everything I have baked in it has turned out perfectly.
