Rainier Cherry Crisp

Preheat the oven to 400 degrees. Place a 9 inch cast iron skillet in a preheated oven and heat 5 minutes. Remove pan from the oven and coat with cooking spray. In a medium bowl, combine the cornstarch, juice, dash of salt and cherries and toss well to coat. Pour cherry mixture into the prepared pan. Weight or lightly spoon the flour into a dry measuring cup and level with a knife. Combine the flour and the next 4 ingredients in a medium bowl and cut in the butter with a pastry blender until the mixture resembles coarse meal. Sprinkle the flour mixture over the cherries. Place the skillet on a jelly-roll pan and bake at 400 degrees for 35 minutes or until the filling is thick and the topping is browned. Remove from the oven and let stand 20 minutes. Serve warm.
