Ingredients

  • 3/4 cup pastry flour, whole wheat
  • 3/4 cup flour, all-purpose
  • 2 tablespoons sugar
  • 1/4 teaspoon salt
  • 4 tablespoons butter cold, 1/2 stick, cut into small pieces
  • 1 tablespoon canola oil
  • 1/4 cup water iced, plus more as needed
  • 1 large egg yolks
  • 1 teaspoon lemon juice or white vinegar

Method

  • Mix together flour, sugar and salt in a medium bowl.
  • Cut in butter with a pastry blender or your fingers until the mixture resembles coarse crumbs with a few larger pieces.
  • Add oil and stir with a fork to blend.
  • Put 1/4 cup water, egg yolk and lemon juice (or vinegar) in a measuring cup.
  • Make a well in the center of the flour mixture.
  • Add enough of the egg yolk mixture, stirring with a fork, until the dough clumps together.
  • (Add a little water if the dough seems too dry.)
  • Turn the dough out onto a lightly floured surface and knead several times.
  • Form the dough into a ball, then flatten into a disk.
  • Wrap in plastic wrap and refrigerate for at least 1 hour.
