When your next day appears busy, prepare some of the dish the night prior. If you chop vegetables for a stir-fry or a lasagna and keep it in the refrigerator, you can serve your delicious meal to your family the next day without the stress of needing extra time. You should store your spices and herbs in a cool dry space out of direct sunlight to avoid flavor loss. Moisture, light and heat can affect the flavor of your spices. It is normally the rule that spices that are ground lose their flavor after they keep for around a year. Spices in their whole form can be stored for between 3 to 5 years. Storing spices in glass containers with a tight-fitting lid will keep them best. Make sure to keep herbs and spices in an area that is cool and dim. Light, heat, and humidity will cause their flavor to weaken. Generally speaking, spices that have been ground will keep their flavor for about one year. Whole spices are hardier, and will retain their robust flavoring for several years. Spices that are stored correctly remain fresher for longer.
