Combine drained pasta with milk, butter, cheese, ham and seasonings. Blend in egg yolks. Beat egg whites until stiff but not dry. Fold into noodle mixture. Spoon all into an ungreased 2-1/2 quart souffle dish and bake for 40 minutes at 350 degrees or until golden brown and slightly puffed. Serve at once.
