Perhaps more common amongst ethnic groups, it's only a matter of time before teff gains the widespread notoriety it deserves for its slightly sweet, nutty taste and impressive nutritional profile.Originating from Ethiopia, teff is considered the tiniest grain in the world. But don't let its size fool you - this small grain in rich in many essential nutrients, including dietary fibre, protein, iron, calcium and amino acids.Eating foods that are high in fibre, like teff, will help maintain proper bowel health and functioning. Fibre also helps to control blood sugar as it slows the absorption of sugars into the bloodstream, meaning it's beneficial in the management of diabetes. This slower digestion also helps you feel full longer, thus aiding in weight maintenance.With a high protein and iron content, teff is an ideal food for vegetarians and vegans who do not get these from animal products. Additionally, the protein and amino acids, particularly lysine, aid in muscle repair, making teff a healthy choice for athletes.Teff also offers an abundance of calcium, which is necessary for healthy bones, teeth and muscles, as well as nerve transmission and hormonal secretion. As for disease prevention, calcium is thought to ward off cardiovascular disease, hypertension, osteoporosis and cancer.Another bonus: teff is gluten free.Teff can be found at health food stores and some ethnic grocery stores. You may find it in different colours, including ivory, red, brown and purple.While the taste gets slightly stronger with the colour, all varieties pack the same nutritional punch so I'd suggest just choosing whichever colour appeals to you.Once you get it home, teff should be stored in an airtight container, in a cool, dry place.To cook, combine one cup of teff with three cups of water in a pot and bring to a boil. Reduce heat, cover and simmer for about 20 minutes or until the water is absorbed, stirring occasionally.If consuming teff as a cereal, you can garnish the hot, cooked grain with fruit and nuts or seeds. Despite its classification as a cereal grain, though, teff's culinary applications extend well beyond breakfast.Here are some suggestions for incorporating this delicious grain into other dishes:- Use it as a thickener for soups, stews, gravies and puddings.- Combine it with vegetables and seeds for a delicious vegetarian burger.- Substitute it for cornmeal when making polenta. Note: this will make the polenta slightly thicker.- As a side dish, as you would use rice, quinoa or millet. It can be served plain or as a pilaf.- Teff flour can be used in gluten-free baking or in combination with wheat flours to provide a nutritional boost.
