What are Job's Tears?
Scientifically known as Coix lacryma-jobi, Job's tears is a type of grass native to Southeast Asia. The name comes from the distinctive tear-like shape of its seeds. It has been a staple in Asian cuisine and traditional medicine for centuries, used in everything from savory soups and porridges to sweet desserts and beverages. The grains are available in both hulled and unhulled forms, with the hulled white version being the most common for culinary use. In its wild form, the seeds have a hard, bony outer shell and are often used for making beads and other decorative items.
The Gluten-Free Misconception
One of the most significant points of confusion surrounding Job's tears is its frequent mislabeling as "Chinese barley" or "adlay barley". This has led many people, especially those with celiac disease or gluten sensitivity, to mistakenly assume it contains gluten and should be avoided.
It is crucial to understand that Job's tears and barley, despite their similar appearance when hulled, are not botanically related. Barley belongs to the Hordeum genus and contains gluten, while Job's tears are part of the Coix genus and are naturally gluten-free. For those with strict gluten-free dietary needs, always check product labels for a gluten-free certification to ensure there has been no cross-contamination during processing.
