In a "shake," you can whip up this old-fashioned confection, Saywell's Lemon Shake, one of the many ice cream specialties at Saywell's Drug Store in Hudson Valley, Ohio (about 25 miles south of Cleveland).
In a blender, combine ice cream and lemonade concentrate. Cover; blend until the mixture is smooth. Pour into a chilled tall glass. Serve immediately. Makes 1 shake.
