Preparation Method
- Preheat the oven to Convection/Bake 350°F. Grease a 9-by-13-inch baking dish with softened butter.
- Make the crisp topping: in a medium bowl, combine flour, oats, sugars and salt. Add diced butter and, using a pastry cutter, work into the dry ingredients until the butter is pea-sized and the mixture is crumbly.
- Make the berry filling: place the berries in a large bowl. In a small bowl, mix the sugar, cornstarch, tapioca and salt. Sprinkle the sugar mixture over the berries and toss gently with your hands to coat the berries evenly.
- Pour the berry mixture into the baking dish and smooth the top. Sprinkle the crisp topping evenly over the berry mixture. Bake until browned and bubbly, about 1 hour. Allow crisp to cool for at least 1 hour before serving.
