                Combine 1 pint of blueberries, granulated sugar, brown sugar, and 1 tablespoon water in a medium saucepan over medium heat. Stir constantly and gently crush the blueberries to release liquid and prevent sugar from burning. Once the mixture boils, add the cornstarch-water mixture. Stir until thickened, about 1 minute. Remove from heat, add the remaining pint of blueberries, lemon zest, and lemon juice. Mix well and let cool completely in the refrigerator.

                Preheat oven to 325°F (160°C). In a medium bowl, combine melted butter, flour, and chopped pecans until well mixed. Press the mixture evenly into the bottom of a 9x13-inch baking dish coated with cooking spray. Bake for 15 minutes and let cool completely. Refrigerate to speed up cooling.
