Selection and storage
Fresh as well as dried oregano are readily available in the herb stores all around the year. If permitted, try to buy fresh herb over the dried form since it is superior in flavor and rich in essential oils, vital vitamins and anti-oxidants like beta-carotene, vitamin C, and folates.
Choose fresh oregano leaves featuring vibrant green color and firm stem. It should be free from mold, discoloration or yellowing. Try to buy dried oregano from the organic farm and processed from authentic sources since it assurances you that the product is free from irradiation and pesticide residues.
Fresh leaves should be stored in the refrigerator kept in a zip pouch or wrapped in a slightly damp paper towel. Dried leaves can be kept fresh for many months when stored in a tightly sealed glass container, and stored in a cool, dark and dry place.
