Pain de Mie/Pullman loaf pan hack?

[meleyna]

So can I successfully pull off a Pain de Mie without buying the specific pan? Meandering around different forums/blogs I've read about placing a sheet pan on top of a regular loaf pan and weighing it down. Won't this create a trapezoid-al loaf? Debating on whether or not I want to invest in such a specialty piece of equipment.

depends on your loaf pan -- but trapezoidal is probably better than having one more pan in the cupboard -- at least until you decide if you're going to make pullman loaves on a regular basis.
