Ingredients

Ingredients For The Crust

  • 1 1/4 cups all-purpose flour (about 150 grams)
  • 1 tablespoon granulated sugar (12 grams)
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter cold and cut into small pieces, (1 stick / 113 grams)
  • 2-4 tablespoons ice water (30 to 60 mL)
  • 1 egg beaten, (for the egg wash)
  • Coarse sugar , for sprinkling on the crust

Ingredients For The Filling

  • 4 cups 4 cups rhubarb stalks sliced into 1/2-inch pieces, (about 1¼ lbs / 560 grams)
  • 1/2 cup granulated sugar (100 grams)
  • 1 tablespoons vanilla (15 mL)
  • 2 tablespoons cornstarch (16 grams)
  • 1/4 teaspoon salt
  • Coarse sugar for sprinkling
  • 1 lemon zest and lemon juice, (about 2 tablespoons of juice)

Optional

  • Handful of Fresh Mint optional
  • 2 tbsp. Triple Sec or Bourbon Liquor optional

Instructions

For The Crust

  • In a large mixing bowl, combine the all-purpose flour, 1 tablespoon of granulated sugar, and salt.
  • Add the cold, cubed unsalted butter. Use a pastry cutter or your fingers to work the butter into the flour mixture until it resembles coarse crumbs with some pea-sized pieces of butter remaining.
  • Drizzle 2 tablespoons of ice water over the mixture and gently mix until the pie dough begins to come together. If the dough is still dry and crumbly, add more ice water, 1 tablespoon at a time, just until the dough holds together when squeezed.
  • Shape the pastry dough into a flat disk and wrap it tightly in plastic wrap. Chill in the refrigerator for at least 30 minutes.

For The Filling

  • Preheat your oven to 375ºF (190ºC). Line a large baking sheet with parchment paper.
  • In a medium mixing bowl, combine the sliced rhubarb, granulated sugar, cornstarch, and salt. Toss well to ensure the rhubarb is evenly coated. (Note: If you are adding strawberries or other fruit, add them now. You need about 4 to 5 cups of fruit total).
  • Transfer the fruit mixture to a medium saucepan over medium-low heat. Stir in the pure vanilla extract, lemon zest, and lemon juice. (If using fresh mint or liquor, add it now). Do not add any water.
  • Gently cook the rhubarb mixture for just 3 to 5 minutes, stirring frequently, until the fruit just begins to soften and release its juices. Remove from heat and let it cool slightly.

Assemble and Bake The Galette:

  • On a lightly floured surface, use a rolling pin to roll out the chilled dough into a circle about 12 inches in diameter. It doesn't need to be a perfect circle! Carefully transfer the rolled dough to your prepared baking sheet.
  • Spoon the slightly cooled rhubarb filling into the center of the dough, leaving a 2-inch border of plain dough all the way around the edges.
  • Gently fold the edges of the dough up and over the filling, pleating and overlapping the dough as you go to create a rustic crust. The center of the filling will remain exposed.
  • Use a pastry brush to lightly brush the pleated edges of the dough with the beaten egg. Sprinkle the egg-washed crust generously with coarse sugar.
  • Bake the galette in the preheated oven for 40 to 45 minutes, or until the crust is deep golden brown and the fruit filling is bubbling.
  • Remove the galette from the oven and let it cool on the baking sheet for at least 10 to 15 minutes before slicing and serving.

Notes

Fruit Variations: You can substitute 1 to 2 cups of the rhubarb with fresh strawberries, blueberries, or sliced apples. You will need 4 to 5 cups of fruit total.
Keep it cold: Ensure your butter and water are very cold when making the crust to ensure a flaky pastry.
Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in a 350ºF oven for 10 minutes to re-crisp the crust.
