Preheat oven to 200°.
To prepare streusel, place egg whites in a large bowl; beat with a mixer at high speed until foamy (about 30 seconds). Gradually add sugar, 1 tablespoon at a time, beating until stiff peaks form (about 2 minutes). Gently fold in almonds, coconut, and 1/4 teaspoon cinnamon. Spread as evenly as possible onto a parchment-lined 15 x 10-inch jelly roll pan.
Bake 2 1/2 hours. Turn oven off; cool meringue in closed oven at least 12 hours or until completely dry. Remove meringue from paper. Crumble meringue into 1/4-inch pieces.
Lightly spoon flour into a dry measuring cup; level with a knife. Combine flour and the next 4 ingredients (flour through 1/4 teaspoon cinnamon) in a bowl; cut in butter with a pastry blender or 2 knives until mixture resembles coarse meal. Stir in meringue pieces.
Preheat oven to 350°.
To prepare filling, combine blueberries and next 7 ingredients (blueberries through orange rind) in a bowl; toss well. Spoon 1/2 cup filling into each of 12 (6-ounce) ramekins or custard cups coated with cooking spray. Top each with 1/3 cup meringue streusel mixture. Place ramekins on a baking sheet; bake at 350° for 10 minutes or until bubbly. Serve warm or at room temperature.
Note: You can also make this dessert in a 13 x 9-inch baking dish. (Bake for 30 minutes or until bubbly.) Or use small skillets like the one above, which we found at Williams-Sonoma. (Bake for 25 minutes.) The recipe makes enough to fill 6 skillets, 2 servings per skillet.
