To make a cherry pie from scratch, start by preparing a homemade pie crust. You can use a simple recipe of flour, butter, salt, and water to make the crust. Once the dough is mixed, roll it out on a floured surface and place it into a pie dish.Next, prepare the cherry filling by rinsing and pitting fresh cherries. In a bowl, mix the cherries with sugar, cornstarch, lemon juice, and a pinch of salt. Pour the cherry filling into the pie crust and dot the top with small pieces of butter.
