CRUST: Using a food processor, pulse together flour, butter, salt and sugar until the mixture resembles coarse crumbs. (If you don’t have a food processor, you can use a fork or your fingers.) Add the vinegar and water until the mixture is doughy. Press into prepared pan in an even layer.
FILLING: Drain any excess moisture from cherries. In a large bowl, combine all of the filling ingredients. Stir to combine. Spread in an even layer over crust.
CRUMB TOPPING: Place all topping ingredients in a food processor. Pulse to make crumbs. Spread evenly over filling layer.
Bake for 50-60 minutes or until a light golden brown and filling is bubbly.
GLAZE: Once completely cool, stir together glaze ingredients and drizzle over pie before cutting into squares.
Notes
*I ran out of cornstarch when making this and I subbed in ½ cup of all purpose flour and it worked perfectly.
