Description

A few notes:

I made this twice in a 9×13-inch pan, and I didn’t think there was enough topping. 6 cups of blueberries, however, definitely is enough for a 9×13-inch pan, so if you like that vessel, I suggest doubling the topping recipe (without doubling the quantities of baking powder and baking soda).

I use a deep, 9-inch pie plate, but if you don’t have one, I think 6 cups of blueberries would be too much for a shallow pie plate.

I also made a few other small changes, so if you want to follow Cook’s Illustrated recipe exactly, follow this recipe.


Ingredients

for the filling:

  • 1/2 cup (3 1/2 ounces) sugar
  • 1 tablespoon cornstarch
  • Pinch salt
  • 6 cups (30 ounces) fresh blueberries, rinsed and picked over
  • zest of one lemon
  • juice from half a lemon

for the biscuit topping:

  • 1 cup (5 ounces) unbleached all-purpose flour
  • 1/4 cup (1 3/4 ounces) sugar
  • 2 teaspoons baking powder
  • 1/4 teaspoon baking soda
  • 1/4 teaspoon salt
  • 4 tablespoons (1/2 stick) unsalted butter, fridge temperature
  • 1/3 cup buttermilk
  • 1/2 teaspoon vanilla extract
  • 2 teaspoons milk for brushing
  • 2 teaspoons turbinado sugar (or not) for sprinkling

for serving:

  • vanilla ice cream or lightly sweetened whipped cream

Instructions

  1. Adjust an oven rack to the lower-middle position and heat the oven to 375 degrees.
  2. For the filling: Stir the sugar, cornstarch, and salt together in a large bowl. Add the berries and mix gently with a rubber spatula until evenly coated; add the lemon zest and juice and mix to combine. Transfer the berry mixture to a 9-inch glass (or not) pie plate or 9×13-inch vessel (see notes above), place pan on a rimmed baking sheet (not necessary if using 9×13-inch pan), and bake until the filling is hot and bubbling around the edges, about 25 minutes.
  3. Meanwhile, whisk the flour, 1/4 cup sugar, baking powder, baking soda, and salt in a large bowl to combine. Cut the butter into small pieces and use your fingers to incorporate the butter into the mixture — it’s ok if the butter gets soft.
  4. Five minutes (longer is fine) before the berries come out of the oven, add the buttermilk and vanilla to flour mixture and mix to combine. Pat mixture into ball or rectangle and roughly divide into 7 or 8 pieces.
  5. To assemble and bake the cobbler: Remove the berries from the oven; increase the oven temperature to 425 degrees. Drop the pieces of biscuit dough on the hot berry filling, spacing them about a 1/2 inch apart. Brush biscuits with milk and sprinkle with sugar. Bake until the filling is bubbling and the biscuits are golden brown on top and cooked through, 15 to 18 minutes. Cool the cobbler on a wire rack 20 minutes (or less) and serve.
