Cut in remaining shortening and butter until particles are the size of small peas. Sprinkle in water, 1 tablespoon at a time, tossing with a fork after each addition. Mix lightly until all flour is moistened. Gather dough together in a ball. Divide in half. Flatten each piece to a 5-inch round. Cover with plastic wrap and refrigerate for 15 minutes.
