What can you use if you don't have a pie funnel?

If you don't have a pie funnel, you can use a metal or ceramic dish placed in the center of the pie to create a vent for steam to escape. Alternatively, you can cut slits in the top crust to allow steam to escape while baking. Another option is to use a small heatproof object, like a crumpled piece of aluminum foil or a small ramekin, to achieve a similar effect.
