The Exquisite Saffron Spice and Its Many Uses
Saffron is often referred to as the most expensive spice in the world, and for good reason. Derived from the dried stigmas of the Crocus sativus flower, it takes approximately 150 flowers to produce just one gram of saffron. This labor-intensive harvesting and processing results in saffron commanding exorbitant prices of $500 to $5000 per pound. The high demand and difficult production of saffron comes from its distinct hay-like fragrance and ability to provide a vibrant yellow color and unique flavor to foods and beverages. Let's take a closer look at this highly-prized spice, its cultivation, uses, and potential health benefits.
Overview of Saffron
Sometimes referred to as "red gold," saffron originated in Greece before being imported to various regions of the world like Spain, France, China, Egypt, Iran, India, and Morocco. Iran now produces over 90% of the world's saffron supply. The majority of saffron in the U.S. comes from Spain. Saffron possesses over 150 volatile and aroma-yielding compounds, which provide its distinct hay-like fragrance and ability to impart vibrant yellow colors and exotic flavors to foods.
Cultivation of Saffron
Saffron comes from the dried red-orange stigmas of the Crocus sativus flower, a species of crocus native to Southwest Asia. The saffron crocus is an autumn-blooming perennial with violet petals and a delicate fragrance. Saffron cultivation requires well-drained, clay-calcareous soils with high organic content. Plant corms are planted 7-15 cm deep in early fall, then flowers bloom in October with stigmas ready for harvest between October and November. Harvesting the delicate saffron stigmas requires patience and skill, which is why it is one of the worlds most labor-intensive crops. The stigmas must be carefully picked by hand in the early morning before heat damages them. Approximately 150 flowers and over 400 hours of labor are required to produce one gram of saffron!
Grading and Processing of Saffron
After harvest, saffron undergoes a labor-intensive process of drying, grading by hand, and packaging. High temperatures can easily damage saffron's color, flavor, and aroma, so the stigmas are traditionally sun-dried or dried over wood-burning fires at low temperatures. Once fully dried, saffron is graded by hand according to ISO standards based on stigma color, flavor, fragrance, and general appearance. The highest grade is Sargol or coup which has dark red-orange threads with no trace of yellow or broken parts. Lower grades include Mancha (brownish red), Rio (light purple), and Sierra (very pale yellow). After grading, saffron is packaged for sale either loose, in strands, or ground into powder.
Uses in Cooking
Saffron is used in cuisines across the world to impart a vibrant yellow color, exotic aroma, and earthy bitter flavor to dishes. Its hay-like fragrance and bitter notes shine through strongly in rice dishes, curries, seafood, roast meats, and bouillabaisse. Here are some popular ways to use saffron in cooking:
- Paella - Traditional Spanish rice dish made with saffron threads, rice, seafood, and vegetables
- Risotto Milanese - Italian rice dish cooked with saffron to give it a bold yellow color
- Swedish Saffron Buns - Sweet buns flavored and colored with saffron
- Indian Biryani - Layered mixed rice dish that uses saffron for fragrance and color
- Moroccan Tagine - Aromatic meat stew that includes saffron
- Provencal Bouillabaisse - Classic French fish stew that relies on saffron for its flavor
- Saffron Cake - Light cake made with saffron threads for a vibrant hue and flavor
When cooking with saffron, it's best to first bloom the strands in hot liquid or crushed between fingers to help release the color and flavor compounds. A little saffron goes a long way, with most recipes calling for just 1-2 pinches or 0.5 grams. Too much saffron can create a metallic or bitter taste.
Other Uses
In addition to being a cherished culinary ingredient, saffron has a long history of use as a fabric dye, perfumery ingredient, and natural remedy:
- Fabric dye - Saffron can be used to dye textiles and other goods bright yellow and orange hues.
- Potpourri - Dried saffron is included in potpourri blends for its delicate fragrance.
- Perfume - Oil extracts of saffron have earthy, floral notes and are blended into high-end perfumes.
- Religious offerings - Saffron's vivid color symbolic of light makes it popular for religious offerings in Hinduism and Buddhism.
- Natural remedies - Saffron has historical and emerging uses to potentially treat depression, PMS, and improve skin quality.
Potential Health Benefits of Saffron
In addition to its culinary and cultural value, saffron contains antioxidants and other bioactive compounds being researched for their health-promoting effects. Some of the potential health benefits supported by preliminary studies include:
Antioxidant Effects
Saffron's bright yellow-orange pigment comes from compounds called crocins, which are potent antioxidants. Antioxidants help neutralize unstable free radicals that can damage cells and lead to inflammation in the body. Studies show saffron's crocins can help suppress oxidative stress and inflammation.
Antidepressant Properties
Multiple studies indicate saffron extract may be effective at reducing symptoms of depression comparable to prescription antidepressants, but with fewer side effects. Saffron's mood-lifting effects may come from enhancing levels of serotonin, norepinephrine, and dopamine in the brain.
Anti-Anxiety Effects
Some animal studies suggest saffron could help reduce anxiety and improve impulse control. The crocin compounds in saffron are thought to interact with neurotransmitters in the brain that regulate mood.
Improved Heart Health
As an antioxidant and anti-inflammatory, saffron may help reduce some risk factors for heart disease. Preliminary studies show it may lower high cholesterol, blood pressure, and levels of triglycerides.
Skin Health
Topical applications of saffron have traditionally been used to brighten complexion and smooth skin. Modern research indicates saffron can inhibit the growth of acne-causing bacteria and reduce signs of aging like wrinkles and crepey skin.
Eye Health
The carotenoids in saffron called crocetin esters have been researched for their effects on macular degeneration and other eye conditions. Clinical studies show potential for saffron to improve vision and retinal function.
Cancer Prevention
Test tube and animal studies reveal saffron's crocin compounds exhibit anti-cancer properties such as slowing tumor growth, prompting cancer cell death, and blocking the spread of cancer. More research is needed to confirm effects in humans.
How to Select and Store Saffron
When shopping for saffron, look for deep red threads sold in clearly marked glass containers displaying the spice name, weight, grade, and origin. Reputable brands will indicate lab testing to verify authenticity and ISO category. For maximum freshness and flavor, purchase saffron threads rather than powder which deteriorates faster. Expect to pay between $7 to $15 per gram for good quality saffron.
To retain saffron's signature color, fragrance, and flavor for up to two years, store it in an airtight container away from light, heat, and moisture. Refrigeration or freezing is ideal.
