Put 1 quart strawberries in a food processor or blender and pulse just
enough to crush but not puree. In a saucepan, mix crushed berries, sugar,
cornstarch, and lemon juice. Cook and stir over medium heat until mixture
thickens. Cool (if necessary in cold water in the sink). Quarter
remaining strawberries and stir gently into cooked mixture. Pour into
cooled pie crust. Chill 6-8 hours before serving. Top with whipped
cream.
