Pate Sucree for Tarts

Pulse flour, sugar, and salt in a food processor until combined, about 4 times. Add butter, and process until mixture resembles coarse meal, about 10 seconds. With processor running, add yolks. Gradually pour in cream; process until dough begins to come together, no more than 30 seconds. Pat dough into a disk, and wrap in plastic. Refrigerate at least 1 hour and up to 2 days.
