Baked Ross and Angie's Poppy seed cake up at Sourdough last weekend. Since there is a statewide fire restriction, including charcoal, I just did it in the 5th wheel oven. (Cast Iron Careth Not From Whence the Heat Cometh; me, 1996) I knew the oven would be way hot on the bottom so I used my diffusor plate from my Camp Chef Dutch oven cap. Worked great.
Everyone should try that cake, it is worth the effort.
