In a mixing bowl, combine flour and butter until mixture resembles coarse crumbs. Gradually add ice water until dough forms. Divide dough in half, shape into discs, and refrigerate for 30 minutes.
Roll out one disc of dough and fit into a pie dish. In another bowl, mix gooseberries, sugar, cornstarch, and lemon juice. Pour filling into pie crust.
Roll out the second disc of dough and place over filling. Seal and crimp edges. Cut slits in top crust to allow steam to escape.
Bake for 45 minutes or until crust is golden brown and filling is bubbly. Cool before serving.
