In a large bowl, combine berries, 1 cup granulated sugar, brown sugar, cinnamon, nutmeg, lemon juice, and 2 tablespoons Urban Meadow all-purpose flour. Toss until berries are well coated and set aside
In another bowl, whisk together remaining Urban Meadow all-purpose flour, granulated sugar, baking powder, and salt. Cut in the cold butter until the mixture resembles coarse crumbs
Pour in the boiling water and stir until just combined. Set aside. Place the mixed berry mixture into a greased baking dish and smooth topping evenly over the berries
Bake for 40-45 minutes or until the topping is golden brown and the fruit filling is bubbly. Serve warm and enjoy!
