Rose, that's a good idea, using a dedicated cast iron pan. If you preheat the pan in the oven, then add boiling water, it should create steam; if you're not seeing steam, then either the pan or water aren't hot enough. And yes, you do have to be very quick about shutting the oven door once you pour the water into the pan. Just spritzing water into the oven won't create enough steam; I think you should give the pan/boiling water another try, this time with your own pan. Good luck! PJH
