Hi. Is there any reason why I can't place a pie with a liquidy custard filling (pumpkin pie) onto a solid metal cookie sheet or similar in order to bake it? The reason being that especially with a thin aluminum pie plate the filling spills while I'm taking it from the counter and into the stove.
I would put the cookie sheet in the oven to preheat with the oven. This ensures better baking results. When you're ready, take the cookie sheet out and put the pie plate on it and return it to the oven.

I preheat the cookie sheet, add my pan with pastry to the sheet in the oven and then pour in my pumpkin filling. Saves accidentally spilling when going from counter to oven, especially with an Ogre I can't hear coming up behind me or cats trying to get in on the fun.
