Raspberry-Rhubarb Biscuit Cobblers

• 2 pints (about 12 ounces) fresh raspberries
• 1 1/2 pounds rhubarb, trimmed and cut diagonally into 3/4-inch pieces
• 1 1/2 cups sugar
• 1/3 cup instant tapioca
• Juice and zest of 1/2 lemon
• 1/2 teaspoon plus a pinch of salt
• 1 cup all-purpose flour
• 1/3 cup cake flour (not self-rising)
• 2 teaspoons baking powder
• 1/2 teaspoon baking soda
• 6 tablespoons unsalted butter, cold, cut into small pieces
• 3/4 cup plain whole-milk yogurt
• 2 to 3 tablespoons heavy cream

1. Preheat the oven to 400F, with racks in the center and lower third.
2. Line a rimmed baking sheet with parchment paper; set aside.
3. In a large bowl, toss together the raspberries, rhubarb, 1 1/4 cups sugar, tapioca, lemon juice, and pinch of salt; stir to combine.
4. Let stand 15 minutes, stirring once or twice.
5. Divide the filling among six to eight 10-ounce baking dishes, or pour into a 2 1/2-quart baking dish.
6. In a medium bowl, whisk together both flours, remaining 1/4 cup sugar, baking powder, baking soda, lemon zest, and remaining 1/2 teaspoon salt.
7. Using a pastry blender, cut in butter until the mixture resembles coarse crumbs.
8. Add the yogurt, and stir with a fork to form a moist dough with the consistency of thick cake batter.
9. Using a large spoon, top filling with dollops of dough, leaving a 1-inch border.
10. Brush dough with cream.
11. Transfer baking dishes to prepared baking sheet; bake, rotating sheet halfway through, until biscuits are golden brown and juices are bubbling, 50 to 60 minutes.
12. (If the biscuits are browning too quickly, cover loosely with aluminum foil during the last 15 minutes of baking.)
13. Cool on a wire rack, at least 1 hour.
14. Serve warm or at room temperature.
15. This easy, biscuit-style topping is dropped by heaping tablespoons onto the fruit filling before baking.
