I need a quick answer for a customer. What stoneware pieces would fit in an oven the size of 8.5 X 11?? I have a customer that bought the medium bar pan but its too big for her oven. Is there another piece that would fit in her oven besides the small bar pan? I was thinking perhaps the loaf pan or the mini baker. What can you use the mini baker for? I've never seen it. How does it compare is size with the small oval baker? TIA for your help.
