Ingredients:

  • 1.5 cups (190g) all-purpose flour
  • 0.5 cup (115g) unsalted butter, chilled and cubed
  • 2 tbsp (25g) confectioners' sugar
  • 0.25 tsp (1.5g) sea salt
  • 4 tbsp (60ml) ice-cold water
  • 4 cups (600g) fresh blueberries
  • 3 tbsp (36g) cornstarch
  • 3 tbsp (45ml) pure maple syrup
  • 1 tbsp (15ml) fresh lemon juice
  • 1 tsp (5g) lemon zest
  • 0.25 tsp (1.5g) ground cinnamon

Instructions:

  1. Combine flour, confectioners' sugar, and salt in a bowl.
  2. Work in the chilled butter using a pastry cutter until the mixture resembles coarse crumbs with a few pea-sized lumps.
  3. Gradually add ice water, one tablespoon at a time, stirring until the dough just holds together.
  4. Press the dough evenly into the bottom and up the sides of a 9-inch tart pan with a removable bottom.
  5. Place the tart shell in the freezer for 10 minutes to lock in the fat.
  6. In a medium bowl, whisk together cornstarch, maple syrup, lemon juice, lemon zest, and cinnamon.
  7. Gently fold in 3 cups of the fresh blueberries until each berry is lightly coated.
  8. Preheat the oven to 350°F (175°C).
  9. Pour the blueberry mixture into the chilled tart shell and smooth the surface with a spatula.
  10. Scatter the remaining 1 cup of fresh berries over the top, pressing them down lightly, and bake for 27 minutes.
