Cilantro
REGION OF ORIGIN
Like its sister spice coriander, cilantro originated in the Eastern Mediterranean, spanning parts of Southern Europe, North Africa, and the Middle East. The wild ancestors of Coriandrum sativum flourished across this old corridor, and cultivation of the herb and spice started in antiquity. Archaeological findings date coriander use to 6000 BCE.
PART & COLOR
Cilantro's bright green leaves are flat and fan-shaped with clearly serrated edges. The spice coriander is produced from the same plant’s tiny fruits.
PRODUCTION
Coriandrum sativum is an annual herb that prefers cool, temperate weather and is typically planted in spring, or in fall where summers are too hot. The leaves can be snipped as soon as the plant reaches 4-6 inches tall, usually 3-4 weeks after planting. To keep it producing for repeated harvests, cut the outer leaves first. The herb bolts quickly as the weather warms, so sow a fresh round of seeds every few weeks for a steady supply.
FLAVOR & AROMA
Cilantro delivers a refreshing, herbaceous flavor and aroma with a bright citrusy punch and a subtle peppery undertone.
However, this same flavor can be polarizing. For many, it adds a delightful freshness, but for others, it tastes overwhelmingly “soapy.” Cilantro contains several aldehydes that some people perceive as soap-like. Genetics appears to play a role: variation near a cluster of olfactory-receptor genes, including OR6A2, has been associated with greater sensitivity to these compounds. Culture and familiarity matter too, and reported rates of cilantro dislike vary widely among populations. The herb is loved precisely in the cultures where the soapy perception is the lowest: Middle Eastern (~3%) and Hispanic (~4%). That helps explain why it's so central to Middle Eastern and Latin American cooking and more divisive in East Asia (~21%) and Europe (~17%).
CULINARY USES
Fresh cilantro leaves are celebrated the world over for their bright, citrusy, and slightly peppery flavor. In Mexican cuisine, cilantro is a must-have ingredient for salsas, guacamole, and tacos. Its bright notes provide the perfect counterbalance to other rich and spicy flavors. In Thai and Vietnamese dishes, cilantro is often sprinkled over salads, soups, and noodles, providing a fresh contrast to the bold and savory elements. Cilantro is also essential in Indian chutneys and Middle Eastern salads and sauces, where it complements other fresh herbs like parsley and mint.
Cilantro pairs exceptionally well with seafood, elevating the delicate sweetness of ceviche and grilled fish in particular. Whether decoratively placed as a simple garnish or taking the spotlight as the dish's central flavor, cilantro has remarkable range in the kitchen.
