1 teaspoon salt
1/4 cup sugar
Scant 1/4 cup ice water
1 egg yolk
1 3/4 cups all-purpose flour
1 cup plus 2 tablespoons butter, cut in 1/2-inch chunks, chilled
Special Equipment: A food processor, a dough scraper
Dissolve the salt and sugar in the ice water, then mix in the egg yolk with a fork until well combined. Place the flour in the bowl of a food processor. Sprinkle over the chilled butter cubes and then pulse on and off, until the mixture is coarse with some pea-sized lumps of butter remaining. With the processor running, add the ice water mixture in a slow stream, then pulse on and off until the dough starts to come together. Empty the dough onto a lightly floured board and gather into a ball. Break off a small chunk at a time and smear across the board with the heel of your hand, then scrape it up with the dough scraper and set aside. Regather together all the smeared bits and form into a ball. Flatten into a 1/2-inch thick disk and wrap in plastic wrap. Place in the refrigerator to chill at least 1 hour and up to overnight.
