Saffron threads are a highly prized and expensive spice made from the dried stigmas of the Crocus sativus flower. Saffron is often used to add a unique and exotic flavor to dishes, and also provides a vibrant yellow-orange color. The threads are very delicate and must be hand-harvested and processed, which contributes to their high cost. Saffron is commonly used in a variety of cuisines, including Middle Eastern, Indian, and Mediterranean, and is often used in dishes such as paella, risotto, and biryani. It is also sometimes used in desserts and beverages for its unique flavor and color.
