For Crust: Blend flour, sugar and salt in processor. Add butter
and process using on/off turns until mixture resembles coarse meal.
Whisk egg and milk in small bowl to blend, then add to processor.
Blend until moist clumps form. Gather dough into ball and flatten

minutes. Cool pie completely in pan on rack.
