Editor's Note: If using frozen rhubarb, measure rhubarb while still frozen, then thaw completely. Drain in a colander, but do not press liquid out. Pastry for double-crust pie (9 inches): Combine 2-1/2 cups all-purpose flour and 1/2 tsp. salt; cut in 1 cup cold butter until crumbly. Gradually add 1/3 to 2/3 cup ice water, tossing with a fork until dough holds together when pressed. Wrap in plastic wrap and refrigerate 1 hour.
