Hi, vnicepeeps!
My pressure cooker recipe book says for a 6 inch dish to cook 26 minutes on position one or 14 minutes on position two.  The bread pudding recipe for a 6 cup bowl says 37 minutes on position one or 20 minutes on position two.  Position one is low (8PSI) and two is high (15PSI).  If your cooker doesn't have a setting option, it's high.  if you would like to see the recipes to help you judge, let me know.  Chris
