BLUEBERRY-LEMON TART

Steps:

• To make the pastry, pulse the flour, sugar, and salt together in a food processor. Put in the chunks of butter, a little at a time, and pulse just until the dough resembles cornmeal. Add the egg yolk and the ice water; pulse again for a second just to pull the dough together. Wrap the dough tightly in plastic and let it rest and chill in the refrigerator for 30 minutes.
• Preheat the oven to 350°F. Using a rolling pin, roll the dough out on a lightly floured surface to a 12-inch circle. Carefully roll the dough up onto the pin (this may take a little practice) and lay it inside a 10 1/2-inch tart pan with a removable bottom. Press the dough into the scalloped edges of the pan and fold the excess dough inside to reinforce the rim.
• Put the tart pan on a cookie sheet and prick the bottom of the dough with a fork. Bake for 20 minutes. Lightly beat the egg white and brush the bottom and sides of the dough with it to seal any tiny holes. Bake for another 10 minutes.
• To make the lemon curd filling, whisk together the eggs, sugar, heavy cream, lemon juice, and zest. Pour the mixture into the tart shell. Spread the blueberries on top of the filling; they will float around and find their own space. Bake for 20 to 25 minutes. The curd will jiggle slightly when done. Carefully lift the tart out of the ring, then slide it off the base onto a plate. Cool to room temperature and slice.
