Nancy, Thanks so much for your comment! I am not adept at working with soy flour, but I don't see why you couldn't try it. Please let me know how it turns out. I have baked in counter-top ovens before, and had no problem with them, so I say give Mrs. Dale's oven a go!
BTW, 175 C. = 347 F., approximately 350 degrees. Good luck!
