Try to buy spices in small amounts if you are not sure you are going to use them within next six months. It would be much better to buy a fresh spice than to use the one that has been stored in your kitchen for more than a year and has lost all its aroma and flavors.
I highly recommend buying seasonings and spices only in specialty stores and shops, preferably by weight. Nowadays, unfortunately most of the brands represented in supermarkets and hypermarkets are not trustworthy. Most of the spices sold in stores contain various chemical supplements, "glutamates" and other substances that are not beneficial to health and do not make spices any better. And of course, you should not buy spices in markets as the spices are stored in the open air there getting dust and bacteria. On top of everything else, they simply lose their flavor and aroma this way. Therefore, custom shops selling spices and seasonings are the best option for purchasing fresh, aromatic and useful spices.
Although many seasonings and spices can last for years if properly stored, I do not recommend storing them for longer than one year. For such a long time, flavor and aroma most probably will weather, the spices will fade and will not be able to enrich the dish with flavour you would expect. I update my collection of spices twice a year: in the fall and in the spring. It is necessary to do this to supply your shelf with new fragrant spices that will reward you with delicious culinary dishes. And yet I want to emphasize that spices do not spoil for many, many years and they do not cause harm to health, but the value of such spices, regarding its taste and aroma, would be totally useless.
Do not store spices near stove or under direct sunlight. Seasonings and spices should be stored a cool, dry and dark place. Keep that in mind. Keep all your spices at a temperature not exceeding 68 ⁰F (20 °С).
By no means pour the spices into a frying pan or cooking pot from the container in which spices are stored. Steam from the pan will penetrate into the container and worsen the spices quality. Use a dry spoon to scoop up the desired amount of spices.
Make a habit of adding individual spices or their blends several times during the cooking process. Depending on the dish, you need to add the mixture at the very beginning of cooking so that the spices are mixed with oil and with enrich the main components of the future dish. Then add the mixture in the middle of the cooking process. And then you should raise the dish to taste on the last stage of cooking. Accustom yourself to tasting your future fine cuisine over and over. This habit will help you check and evaluate the taste balance of your dish.
