Ham and Cheese Breakfast Tarts
If you prefer, use a food processor to prepare the pastry. In a food processor combine flour, sugar, salt, butter, and egg. Cover and process with on/off pulses until mixture is crumbly. Using the 2 to 4 tablespoons milk, add 1 tablespoon of the milk to food processor; cover and process with on/off pulses. Repeat adding milk, 1 tablespoon at a time, and pulsing until flour mixture forms a smooth ball. Remove from processor. Divide pastry in half; form halves into balls. If desired, cover with plastic wrap and chill until ready to use.
