I am normally a good baker. i found a recipe for egg custard pie. i told my husband 2 go 2 the store to get the ingredients (only 1 person per family is allowed in the store and i cannot be trusted because i come home with a whole bunch of junk food lol). 1 of the ingredients were pie crust, i told him the pie crust are in the refrigerated section near the eggs and where the cookie dough is. he came home with pie crust from the freezer in a pie plate already....i have never seen these in my life and the pie dish was not deep. this was the outcome of using pie crust i have never made before. apparently the egg custard somehow got under the pie crusts while baking, and that big bubble in the middle is the pie crust
