Should I thaw before cooking?
All unbaked products are designed to be cooked from frozen. Thawing will do little in reducing the cooking time, and may give undesired results. When thawing, the water in the gravy will thaw first and actually leave the gravy. While cooking, the water may not reincoperate into the gravy, and the pie may be very liquidy as a result. The water may also soak into the crust and make it soggy as well.
