The tropical Hibiscus flower is a very popular item in spice shops all over the Middle East and Europe. It can be used in both sweet and savoury dishes. Hibiscus tea is also very widely enjoyed for both its flavour and health benefits. It can be chilled for a decent, tart drink. Dried hibiscus flowers can also be burnt and used as hair dyes.
Hibiscus tea is made from a mixture of dried flowers, leaves and the dark red calyces of this plant. In cooking it is used more than a garnish rather than for its flavour. When the dried, red flowers are seeped in boiled water, it releases a dark red colour and a very tart flavour that works well in both teas, cocktails and sauces.
The most important point is that dried herbs and spices can never go bad if they are kept dry. Yes, the potency is lost, but it will still influence the flavor of your cooking.
Seeds, roots, leaves and flowers last longer than crushed or ground herbs and spices. When you are preparing to store your dry herbs and spices it is vital that they are completely dry. A good indication is to rub it with your finger to check if it crumbles. As oxygen degrades dried herbs and spices over time, you should store them in airtight containers. Glass jars with sealable lids are perfect, and so are metal tins. Plastic won’t do for long terms storage. Sunlight also degrades dried herbs and spices; therefore, it should be stored in a dark cabinet that is both cool and dry. If your spice rack is near the stove or cooker, steam will degrade your herbs and spices each time you open the container while cooking. When buying in bulk, you should always store only some of the dried herbs and spices in a glass or metal container. Each time you open it, it is exposed to the elements. When buying in bulk it is useful to label your containers with the purchase date and discard date.
