Diane, I'm not sure what size sheet tray you're planning to use, but you'll probably need to almost double the amount of fruit filling if using a 13 X 18 inch sheet tray. PJ said the filling and top crust measured about 1 1/4 inches high in her pan, so if your sheet tray is one inch high, but also fans out a bit, double the amount of filling should work nicely. You may want to place a pan under the cobbler, just in case the filling bubbles out a bit when it boils. Barb@KAF
