Goji berries are wonderful, little bits of joy used in East Asian food and medicine. It's an excellent addition to your diet; helping eyesight, protecting the liver, and boosting immune function. Of course, they have high antioxidant qualities as well, so get-to-eating!
You can eat them like berries (they're usually dried), or you can steep them in tea like I do (it's so refreshing!). They taste a little like dried cranberries on their own, but they lose some of their sweetness and tang in tea. Pick up a packet of these at any Chinese supermarket.
