Berry pie is a delicious dessert made with a flaky crust filled with a mixture of fresh or frozen berries. Common berries used include blueberries, raspberries, strawberries, and blackberries. The berries are often sweetened with sugar and thickened with cornstarch or flour to create a juicy filling. Typically baked until the crust is golden brown, berry pie can be served warm or cold. It is often enjoyed with a scoop of vanilla ice cream or a dollop of whipped cream. This dessert is popular in many cultures and is especially favored during berry-picking seasons.
