A mixture of cooked and fresh berries helped make this pie a family favorite.
Combine strawberries and water in saucepan. Cook until just softened, about 4 or 5 minutes. (Let frozen berries thaw; heat but don’t cook them.) Mix together cornstarch, sugar, and water until smooth; add to hot berries. Cook over medium heat until clear. Add lemon juice; immediately remove from heat and let cool. Place sliced berries in cooked pie shell. To assemble pie, pour cooked mixture over berries, top with whipped cream, and garnish with whole berries.
