Yeah they do. It’s a pretty serious oven. They sourced some recycled old school firebricks. There’s cement, 2layers of fire insulation and more cement. I actually have a picture somewhere of my father in law inside the oven building it. You can fit 2 adults in there. Reminds me to be good to the wife, as I don’t want to end up in there with a roaring fire.... To make the pizzas, they heat soak it for hour and a bit. Then they scrape out all the burnt wood and ashes. They mop the floor before putting in the pizzas or bread. It will stay warm for several hours. It’s not sealed like the KK but does retain heat for quite sometime. It’s still warm in the morning after an evening cook. I think it more to do with the retention of heat in the bricks and cement. They do roasts, lasagne, turkey and all other sorts. We have Christmas there and they will fire this up on Christmas Day for lunch. A roaring fire on 40 degree Celsius days.... not quite the cold Christmas’s you guys have. The salamis are good fun. It’s a early morning start cutting up the meat. We have had to change up the recipe over the years. We do much less salt nowadays. We put in fennel seeds, chilli and other herbs and spices. It hangs like that for weeks. We also make fresh sausages as well. Homemade is always great! Sent from my iPad using Tapatalk
