Roasters Rule!
What a terrific treasure you pulled out of that trash! It's a real beauty - and Nesco was/is one of the best roasters made (Westinghouse was the other excellent roaster). Nesco used "Circle of Heat" - as did most others, but Nesco coined the name. There are no elements on the bottom, only elements around the walls of the roaster. Yes, it roasts a turkey, but so much more. I bake in mine - if you are making a 9x13 cake the pan will fit perfectly inside. Also great for making big quantities of speghetti sauce, soups, baked beans. What's more, there are no moving parts, so they last practically forever. Enjoy your wonderful find and I tell us about all the wonderful things you make in it!
