Rustic Blueberry Tart

Blueberries are IT for me. Sitting down and eating a pint is no big deal. Sharing is a no-no. And finding new ways to incorporate them into baking is a must.

  • 1 1/2 cups all-purpose flour
  • 1/2 cup confectioner’s sugar
  • 1/4 teaspoon salt
  • 1 stick plus 1 tablespoon 9 tablespoons; 4 1/2 ounces cold unsalted butter, cut into small pieces
  • 1 large egg

Egg Mixture

  • 1 egg
  • 1 teaspoon cinnamon

Blueberry Sauce

  • 2 cups blueberries frozen works fine
  • 1 cup heavy cream
  • 2 teaspoons lemon juice
  • 1/4 cup powder sugar
  • 2 teaspoons cornstarch
  • 4 ounces white chocolate roughly chopped


  1. Pulse the flour, sugar and salt together in the bowl of a food processor.
  2. Drop in the pieces of butter into the processor and pulse until the butter is coarsely cut in. (small pieces)
  3. Gently mix the yolk then slowly add into the food processor on low.
  4. Once the egg has been added, pulse for 10 second increments until the dough starts to pull together and clumps.

  5. Remove dough from processor and place on a parchment lined cookie sheet. Using your hands, gently start to press the down down and out. (Not tearing) You are trying to spread the dough over the pan and a rustic oval. Once the dough is mostly flat, take a fork and pierce the dough about every inch or so. (Covering entire tart)

  6. Place dough in 350 degree oven for 10 minutes.

For Blueberry Sauce

  1. Place all ingredients in a sauce pan and stir over medium-low heat. Allow the corn starch to work and thicken the sauce. Once the sauce starts to thicken, remove from heat. (About 10 minutes)

  2. After the tart has baked for 10 minutes at 350 degrees, you will then remove it and generously brush entire tart with egg mixture (one egg and cinnamon in a small bowl beaten until combined).

  3. Pour blueberry sauce over tart and allow it to get right to the edges. Place tart back into oven for 8 minutes. (This is where the indention and groves your fingers made in the dough help, as they are natural divets for the sauce to sink into)

  4. Remove tart and sprinkle white chocolate over the top, then place back in over for about five minutes, or until the chocolate is melted.
