Ingredients
2 1/3 cups cake or pastry flour
1/3 cup sugar
1/2 pound (2 sticks) unsalted butter, chilled, cut into small pieces
2 egg yolks
1 or 2 tablespoons heavy cream

Directions
In a food processor fitted with the steel blade, combine the flour and
sugar. Add the butter and process until the texture resembles fine meal.

In a small bowl, whisk together the yolks and 1 tablespoon of the cream. Scrape into the machine and
process until a ball begins to form, using the additional tablespoon of cream, if necessary. Remove
the dough from the machine, and on a lightly floured surface, press down into a circle.

Wrap in plastic wrap and refrigerate for at least 1 hour.
