Question: what is the difference between double crust pie and single crust pie?
Answer: Pie is a baked dish featuring a fruit filling encased in dough, which is called a pie crust once baked. Pie doughs can be made into a double-crust (filling is fully encased), single-crust (open top, with a single blind-baked bottom crust), or somewhere in between (fancy lattice-top crust).
