Orange Julius Recipe. The Orange Julius drink started out being my favorite when I went to the Mall as a teenager in the 1970's, so it has endured the test of time. Everyone had to get one. But they kept the recipe a secret for a long time. Be sure to read the History note at the bottom of the page. It's an easy recipe, the original smoothie.
Since kohlrabi is a cool-weather crop, most gardeners plant it in late winter or early spring and again in the late summer or early fall in order to get two crops a year.
Kohlrabi's popularity has seemed to wane in the US over the years, though based on its appearance in a number of antique cookbooks I've come across, it was far more common in the recent past. Kohlrabi comes in two varieties: one deep purple and the other vibrant green. Both have pale green to white flesh.
