If you want to get really expensive they'll sell you an old fashioned wood stove just like my great aunt Ada had... hers was dark green enamel and had the well for hot water on the side. And she lived in Pennsylvania, in PA Dutch country, so it sort of fits with the Lehman's thing.
I wish I had her recipe for ruhbarb pie... she had a kitchen garden would cool the pies on her open double dutch doors after baking them in her wood oven. She never would let the family install an electric or gas stove... cooked on that wood oven up until the day she died.
I have ordered lots of the "granny ware", use it on the stove and in the oven and on the grill. Great stuff!
