A frothy orange milkshake just like those sweet drinks you used to find at the mall. In 1926, a Mr. Julius Freed opened an orange juice stand in Los Angeles, only to find that although his product was excellent, business was not. One of Freed’s associates, a chemist by trade, decided to experiment with orange juice augmentation formulas, and through said finagling formulated a familiar orange milkshake concoction that is with us to this day.This recipe first appeared in Season 12 of Good Eats.
Pour 6 1/2 fluid ounces of the orange juice Make sure you zest your oranges before collecting the juice. into an ice cube tray and freeze until solid, approximately 2 hours. Store the remaining 2 fluid ounces juice and the zest in an airtight container in the refrigerator until ready to use.
Combine the frozen juice cubes, reserved orange juice and zest, milk, confectioners' sugar, and vanilla in a blender and blend until smooth and slushy, 30 to 45 seconds. Serve immediately.
