My dad would always stop our car on the side of the road in Maine and say, "I smell blueberries." He had a pail ready. Then Mom would bake the wild berries in a cornmeal crust to make this homey tart. —Priscilla Gilbert, Indian Harbour Beach, Florida

Ingredients

  • 2 cups all-purpose flour
  • 1/3 cup sugar
  • 1/4 cup yellow cornmeal
  • 2/3 cup cold butter, cubed
  • 1/2 cup buttermilk
  • FILLING:
  • 4 cups fresh blueberries
  • 2 cups fresh blackberries
  • 2/3 cup sugar
  • 1/3 cup all-purpose flour
  • 2 tablespoons lemon juice
  • 1 large egg, beaten
  • 2 tablespoons turbinado (washed raw) sugar or coarse sugar
  • Whipped cream, optional

Directions

  1. In a large bowl, mix flour, sugar and cornmeal; cut in butter until crumbly. Gradually add buttermilk, tossing with a fork until dough holds together when pressed. Shape into a disk; cover and refrigerate 30 minutes or overnight.
  2. Preheat oven to 375°. On a lightly floured surface, roll dough into a 14-in. circle. Transfer to a parchment-lined baking sheet.
  3. In a large bowl, combine berries, sugar, flour and lemon juice; spoon over crust to within 2 in. of edge. Fold crust edge over filling, leaving center uncovered. Brush folded crust with beaten egg; sprinkle with turbinado sugar.
  4. Bake 55-60 minutes or until crust is golden brown and filling is bubbly. Using parchment, slide tart onto a wire rack to cool. If desired, serve with whipped cream.
