Here’s one way to cover a pie for transportation or storage to keep things off of it and out of it without ruining the top of it. This is especially useful for pies with soft-ish tops that plastic wrap or aluminum foil would stick to and mar.
This was a cream cheese type pie and I didn’t want the top spoiled, but I needed to refrigerate it overnight (as I recall).
I took some plastic wrap and formed it into a loose ball and placed it in the center of the pie. Then I gently wrapped another piece over the entire pie. The ball in the center created a dome effect. This might not work with meringue or whipped cream toppings. However, whipped cream topping could probably be reworked in the middle. Use your discretion.
