Instructions

  1. In a large bowl, mix oats, flour, walnuts, brown sugar, cinnamon, ginger and salt. With your fingers or a pastry blender, rub or cut butter into oat mixture until coarse crumbs form. Cover and chill.
  2. Rinse rhubarb; trim off and discard green parts of stalks. Cut red parts into 1/2-inch thick slices; you need about 2 cups of sliced rhubarb. In a large bowl, combine granulated sugar, cornstarch, raspberries and rhubarb and mix gently to coat. Pour into a shallow 2 to 3-qt. baking dish and sprinkle evenly with the topping.
  3. Bake in a 350° oven until topping is golden brown and fruit is bubbling, about 45 minutes. Serve warm or at room temperature with ice cream or whipped cream.
