Lemon Grass is an herb that has a pungent citrus flavour – hence why it is called lemon grass. It is widely used in Asian cuisine and for medicinal purposes worldwide. It is also most commonly used in teas and the dry form, whether powder or pieces is easy to store for daily or occasional use.
In its dry form, it is used for meat rubs. It gives exceptional depth to curries and stews and is very popular in dishes that come from the Asian Continent. Using lemon grass with poultry, meat, fish and seafood adds acidity to the flavours. In African countries, it is mostly used as tea. The oil extracts are used as a preservative of foods.
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.
