Fluting the edge of a pie crust: To flute the edge of a pie crust, gently push the inner edge out with one thumb while pinching in from the opposite side with the other thumb and index finger. Continue forming evenly spaced triangular points all the way around the edge of the crust until it's completely fluted.
