• Line the bottom of a 9" pie plate with one of the two pie crusts.
• If using frozen fruit, let the mixture stand for 30 minutes or until partially frozen.
• Mix mulberries with orange zest, and orange juice.
• In another bowl, mix sugar, flour, and salt.
• Stir flour into the mulberry mixture.
• Pour the mulberry mixture into the prepared pie crust.
• Dot with butter, and top with the remaining pie crust, in a lattice fashion.
