In a large bowl, combine the sugar, cornstarch, juice, and vanilla to form a paste. Add the cherries and coat.
Pour the cherry mixture into the bottom crust of the pie and then cut the top crust into strips to form a lattice pattern. Brush the lattice with milk and sprinkle with sugar.
Bake at 425 for 45 minutes.
