June 24, 2014

Pie dough

  • 1 cup all-purpose flour
  • ½ teaspoon sugar
  • 2 tablespoons fine yellow cornmeal
  • ½ teaspoon salt
  • ½ cup (1 stick) butter, cubed and chilled
  • 2–4 tablespoons ice water



Tarragon Streusel Topping

  • ½ cup all-purpose flour
  • ¼ cup sugar
  • 1 tablespoon tarragon, roughly chopped
  • 2 ounces butter, cubed and chilled



  1. 1½ pounds plums, sliced into ½-inch pieces
  2. ⅓ cup sugar
  3. 1 tablespoon all-purpose flour
  4. ¼ teaspoon salt


Make pie dough. Place flour, sugar, cornmeal, and salt in a food processor. Pulse to combine. Add chilled butter and pulse a few more times, until mixture has pea-sized chunks of butter. Drizzle in 2 to 3 tablespoons ice water and pulse until dough holds together when squeezed. Add another tablespoon water if needed. Form dough into a disk, cover with plastic wrap, and refrigerate for 30 minutes.

Make streusel topping. In the same food processor, add the flour, sugar, and tarragon. Pulse to combine. Add butter and pulse until crumbly. Pour into a small bowl and refrigerate until needed.

Preheat oven to 400°F. Combine plums and sugar in a large bowl. Set aside. Remove pie dough from refrigerator and roll out on a floured surface to fit an 11-by-7-inch rectangular tart pan or a 9-inch round tart pan. Place the dough gently into the tart pan and ease it into the corners, pressing with your fingers. Roll a rolling pin over the top edge of the pan to remove excess. Drain the plum/sugar mixture using a sieve and return mixture to bowl, discarding drained liquids. Add flour and salt and gently toss until plums are evenly coated.

Shingle plum slices into prepared pan. Scatter streusel topping on top. Place tart on rimmed baking sheet and bake for 40 to 45 minutes or until golden brown. Cool 30 minutes before serving.

Makes 6 to 8 servings
