I've been attempting to bake my pies that I bake in my regular glass pie plates in disposable pie tins in order to give them to friends. I've baked an apple pie, a chocolate walnut pie, a pumpkin pie, and a pecan pie. The centers in all these pies were undone or mushy, just not the same consistency that they are in the glass pie plates. I found a heavier aluminum tin on kitchendance.com, but this did not solve the problem either. They come out perfect in glass - not-so-perfect in the tins. Has anyone had a similar problem and found a solution?
