Energizing and nutritious, buckwheat is available throughout the year and can be served as an alternative to rice or made into porridge. While many people think that buckwheat is a cereal grain, it is actually a fruit seed that is related to rhubarb and sorrel making it a suitable substitute for grains for people who are sensitive to wheat or other grains that contain protein glutens. Buckwheat flowers are very fragrant and are attractive to bees that use them to produce a special, strongly flavored, dark honey. Buckwheat is also ground into flour, available in either light or dark forms, with the darker variety being more nutritious. Since buckwheat does not contain gluten, it is often mixed with some type of gluten-containing flour (such as wheat) for baking. In the United States, buckwheat flour is often used to make buckwheat pancakes, a real delight, especially for those allergic to wheat. Buckwheat is sold either unroasted or roasted, the latter oftentimes called "kasha," from which a traditional European dish is made.
