When we moved in our house in Baltimore we discoverd an Oriole stove in the basement. It's a cast-iron, several hundred pound beast that I adopted for beer brewing. Sitting on top is my faithful 50-Liter, stainless steel vessel with bottom valve that I use for brewing beer. The oven portion of this is not easy to use however. It has a gas regulator but no thermostat. You turn it on, let the temperature stabilize and monitor the intermal temperature . . . adjust the gas, stabilize, measure, repeat. It can easily achieve 700-deg-F.
When we moved to Columbus, we took it with us to our new home. I don't often get possessive of material things, but this mass of cast iron is kind of special. Since the big lightning strike, we've been without an oven and have had to use this thing to bake. I'm getting better at it and have cooked a bunch of focaccias on it lately. Tonight I baked one for a big potluck next door. (It was eaten quickly, always a nice feeling.)
If I can stabilize the temperature a bit better, I'm considering doing some ultra thin pizzas. Stay tuned for the results.
