Put shortening in bowl. Pour on boiling water and milk. Whip with a fork until mixture is smooth and thick like whipped cream. Add flour and salt. Stir quickly with round-the-bowl strokes until it "cleans" the bowl. Form into a ball with hands.

Divide ball into two equal balls and roll for two pie crusts. Press crusts into pie plates and prick with fork. Bake at 425 degrees about 15 minutes or until light brown. Fill crusts with cream filling or can be frozen for later.
