Best oval banneton size for Lodge 9-inch cast-iron combo cooker?
Hi folks, after years of (often fairly successfully) proofing my loaves just lying flat, I'm getting into bannetons. I also am starting to accept that no home oven steam strategy is going to work nearly as well as baking in a Dutch oven, so I'm using my terra cotta tiles less and less and my cast-iron combo cooker more and more.
The combo cooker is great, but it also obviously constrains my loaf size. I bought a 9-inch round banneton and that works well with the combo cooker (whose flat bottom surface is also 9 inches), but now I want to get a couple of oval bannetons so I can bake better batards.
Given the diameter of the combo cooker (9 inches across the flat bottom, and about 9.5 inches at the rim), am I stuck with this small oval banneton (8.75 inches long at the rim)? Or do you think I can get away with using the regular-sized oval banneton (10 inches long at the rim)? Also, if the Breadtopia products aren't the best option, I'm very open to other recommendations.
Thanks for any thoughts! D
