Double Berry Cobbler

Combine 2 cups blackberries and 1 cup strawberries. Add 1/3 cup sugar and 1/4 cup cornstarch to the berries. After adding the dry ingredients, add 1 tablespoon lemon juice. In a separate bowl, combine 1 cup flour, 1 cup sugar, 1 teaspoon baking powder, and 1/4 teaspoon kosher salt. Scramble 1 egg, then add it to the dry mixture with a fork or hands until crumbly. Add this topping on top of the fruit mixture. Add 1 stick of melted unsalted butter, swirling it around to ensure even distribution. Bake at 350°F (175°C) for 35 minutes until nice and golden brown. Cool for 30 minutes before serving.
