Step 1. For the dough: In a medium mixing bowl, whisk together the flour, sugar, and salt. Set aside. In a liquid measuring cup add the egg and lightly beat with a fork. Add enough heavy cream until the mixture reaches 1/3 cup. Whisk together to combine. Set aside.
Step 2. Add the chilled cubes of butter to the flour mixture and begin cutting the butter into the dough using a pastry cutter or just your hands (if you’re feeling really rustic). You are looking for pea-sized morals of butter and the for the mixture to look like moist sand. Add in the lemon juice and zest. Slowly drizzle in the egg/cream mixture (up to ¼ cup) and mix to the dough begins to come into shape. Transfer dough to a lightly floured work surface. Flatten into a disc and cover with plastic wrap. Allow the dough to rest in the refrigerator for 1 hour. (Note: dough will last in the fridge up to 3 days.)
Step 3. Preheat the oven to 400 degrees F. Line a sheet pan with parchment paper. For the filling. In a medium mixing bowl combine the berries, sugar, salt, lemon zest, lemon juice, and cornstarch. Stir to combine. Set aside.
Step 4. Once the dough has rested take it out of the fridge and allow to soften up a bit so it is easier to work with. Roll the dough out until it reaches 12-inches in diameter. Take the filling and place it in the center of the dough. Spread it out, leaving roughly a 1-inch perimeter around the doughs edge. Begin folding the edges of the dough over the berries. Brush pastry generously with leftover egg and cream mixture. Sprinkle remaining sugar on the crust. Bake for 35 – 45 minutes or until the crust of golden brown and the fruit is bubbly. Allow to cool before serving.
For the whipped cream. Place a metal mixing bowl and metal whisk into the freezer for 10 to 15 minutes. Doing this will allow the cream to stay cold and create stiff peaks quicker. Place the sugar into a mixing bowl and add the heavy cream. With a hand mixer or metal whisk, whisk just until the cream reaches stiff peaks, about 7 to 9 minutes. Add the vanilla extract in one tablespoon increments until desired taste is reached. Store in an airtight container for up to 10 hours. When ready to use, whisk for 10 to 15 seconds to reincorporate the air back into the cream.
