In the bowl of a food processor combine flour and sugar. Add butter and process until mixture resembles coarse meal, 10-20 seconds.
In a small bowl lightly beat egg yolks and add ice water. With the machine running, add the egg mixture in a slow steady stream through the feed tube. Pulse until dough holds together without being wet or sticky. Be careful not to process more than 30 seconds. To test squeeze a small amount together. If its crumbly, add more ice water, 1 tablespoon at a time. Divide dough into 2 equal balls. Flatten each ball into a disk and wrap in plastic. Transfer to the refrigerator and chill at least one hour.
Makes 1 pie dough-Top & Bottom.
