Preheat oven to 400 degrees F.
Mix fruit, tapioca, sugar, lemon juice and extract in a bowl. Let stand 15 minutes. Fill pastry lined 9 inch pie plate with fruit mixture. Cover pie with top crust; seal and flute edge. Cut several slits in top to permit steam to escape. Bake 1 hour or until juices form bubbles that burst slowly. Cool.
