By now, most of us have at least heard of the term “superfood.”  These amazing foods have quantities of vital nutrients, minerals and antioxidants that can be hard to find elsewhere in such concentrated amounts. In addition, many of these foods are found in faraway regions of the earth and may parish before reaching our shelves. Enter superfood powders! These dried powders are extremely versatile and easy to add to any diet. Here, shrimp tostadas use Turmeric, from the ginger family, Acai powder, Baobab powder, Lucuma powder and dried goji berries. Turmeric and Acai are probably familiar to most, but Baobab, Lucuma and Goji berries may be new to some. Baobab trees grow in arid parts of Madagascar, Africa and Australia. The fruit of these trees contain seeds that are dried and made into powder.  It has a mild citrus flavor that is extremely versatile for adding to dressings, marinades, smoothies, or stirring into oatmeal and yogurt. Lucuma is an interesting fruit that is similar in appearance and texture to an avocado, but is orange inside has a mild, sweet maple flavor that works well in baked goods or as a substitute sweetener. Finally, dried goji berries have a delightfully sweet flavor and can be ground into a powder using a food processor or coffee bean grinder.  They add a sweet component to the spicy rub used for the shrimp in this case, but left whole, goji berries are a colorful, delicious addition to baked goods and an easy garnish for salads and parfaits.  All of these health boosting powders can be found at most natural or organic foods stores and many grocery stores.
