Directions
<ol class="no-list-style"><li class="MethodStepper"><h4 class="step-title">Step 1</h4>Prepare your pastry first. In a large bowl (or food processor), whisk together the flour, salt, and sugar. Add the cold cubed butter and cut it in using a pastry cutter, two forks, or pulse in the food processor until the mixture resembles coarse crumbs with some pea-sized butter pieces still visible. These butter pockets will create flaky layers in your crust as they melt and release steam during baking.</li><li class="MethodStepper"><h4 class="step-title">Step 2</h4>Drizzle in ice water, 1 tablespoon at a time, mixing gently after each addition until the dough just begins to come together. You may not need all the water – stop when the dough holds together when pinched. Gather the dough into a disc, wrap in plastic wrap, and refrigerate for at least 1 hour. Cold dough is essential for a flaky crust as it prevents the butter from melting too quickly.</li><li class="MethodStepper"><h4 class="step-title">Step 3</h4>While the dough chills, prepare your filling. In a large bowl, gently toss the blackberries with sugar, cornstarch, lime zest, lime juice, and salt. The cornstarch will thicken the juices as the berries bake, preventing a soggy bottom crust. Let this mixture sit for 15 minutes so the berries begin to release their juices.</li><li class="MethodStepper"><h4 class="step-title">Step 4</h4>Preheat your oven to 190°C (375°F) and line a baking sheet with parchment paper. On a lightly floured surface, roll out your chilled dough into a round approximately 30cm (12 inches) in diameter and about 3mm (1/8 inch) thick. Don't worry about perfect edges – galettes are meant to be rustic!</li><li class="MethodStepper"><h4 class="step-title">Step 5</h4>Gently transfer your rolled dough to the parchment-lined baking sheet. Using a slotted spoon, pile the blackberry filling in the center of the dough, leaving about a 5cm (2-inch) border all around. The slotted spoon helps leave behind excess juice that could make your crust soggy.</li><li class="MethodStepper"><h4 class="step-title">Step 6</h4>Fold the edges of the dough over the filling, pleating as you go around. The center of the galette will remain open, showing off the beautiful berries. Brush the folded dough edges with beaten egg wash, which will give your crust a beautiful golden shine. Sprinkle the crust with coarse sugar for a delightful crunch and sparkle.</li><li class="MethodStepper"><h4 class="step-title">Step 7</h4>Bake for 40-45 minutes, or until the crust is deeply golden and the filling is bubbling. If you notice the edges browning too quickly, loosely cover them with foil. The bubbling filling is your visual cue that the cornstarch has activated and thickened the juices.</li><li class="MethodStepper"><h4 class="step-title">Step 8</h4>Allow the galette to cool for at least 15 minutes before slicing – this resting time helps the filling set up properly. Serve warm or at room temperature, perhaps with a dollop of whipped cream or vanilla ice cream. The galette is best enjoyed the day it's baked, when the crust is at its crispest, but will keep covered at room temperature for 2 days.</li></ol>
