It's best to eat this soon after it comes out of the oven. It will keep nicely for a couple of days, but be sure to re-heat it in a 300 degree oven before serving so the topping can re-crisp.
1 tablespoon unsalted butter at room temperature, for pan
Fruit Filling
3/4 cup granulated sugar
2 tablespoons cornstarch
1/4 tsp fine sea salt
4 cups rhubarb, cut into 1 or 2-inch pieces
1 tablespoon vanilla extract
Biscuit Topping
1 1/4 cups all-purpose flour
3/4 cups unsifted cake flour (like Lily)
1 tablespoon granulated sugar plus 1 tablespoon to top biscuits
1 tsp baking powder
1/2 tsp fine sea salt
1/2 cup cold unsalted butter, cut into small cubes
3/4 cup plus 1 tablespoon cold buttermilk
1/4 cup heavy cream
Preheat the oven to 375 degrees. Butter a 3-quart baking dish.
To make the fruit filling, rub the sugar, cornstarch and salt together in a bowl. Add the rhubarb, toss until evenly coated, then gently stir in the vanilla. Spoon the fruit into the prepared pan, being sure to scrape the bowl well.
To make the biscuit topping, whisk the flours, 1 tablespoon of the sugar, the baking powder, and salt together in a bowl. Add the butter and toss until evenly coated. Using your fingertips or a pastry blender, cut in the butter until the size of large peas. (Alternatively, you can put the dry ingredients in a food processor and pulse to combine. Add the butter and pulse until the butter is the size of large peas, then transfer to a bowl.) Combine 3/4 cup of the buttermilk and the cream, then pour into the dry ingredients and stir just until the dry ingredients are moistened. The dough will be crumbly, with large pieces of butter still visible.
Turn the dough out onto a lightly floured work surface and gently press the dough together to form a rectangle, then roll out to a thickness of 1/3 inch. Cut out twelve 2 1/2- inch round or square biscuits, re-rolling the scraps as needed. Place the biscuits atop the fruit filling, then brush the tops of the biscuits with the 1 tablespoon buttermilk and sprinkle with the remaining 1 tablespoon of sugar.
Bake for about 50 minutes, or until the biscuits are golden and the filling is bubbling all over. Serve Warm.
Storage: Covered with a tea towel, the cobbler can be stored at room temperature for up to 2 days. Reheat in a 300 degree oven until warmed through.
