I have a question about the recipe "Steamed Brown Bread" from thirschfeld. What other options can we use to bake it in? I love the can idea but most can linings have BPA in them and that is obviously unappealing. Eden organics bean cans don't have BPA but they're lined with something else that is probably kind of bad to heat in contact with the bread. Thoughts for alternate, non-toxic baking molds for this lovely recipe?
