Overview

Coriander (Coriandrum sativum) is an annual herb in the family Apiaceae, native to regions spanning from southern Europe and North Africa to southwestern Asia. The plant produces two distinct ingredients: the fresh leaves, commonly called cilantro or Chinese parsley, and the dried seeds, called coriander. The leaves have a bright, citrusy, slightly soapy flavor that polarizes eaters, while the seeds are warm, nutty, and floral with a hint of citrus.

Origin and history

Coriander is one of the oldest cultivated herbs, with archaeological evidence of its use dating back to the Neolithic period. Seeds have been found in the Nahal Hemar cave in Israel from around 6000 BCE and in the tomb of Tutankhamun in Egypt from the 14th century BCE [1]. The plant is mentioned in the Sanskrit Vedas and in ancient Greek and Roman texts, where it was used both as a culinary herb and a medicine. Coriander spread along trade routes across Asia, the Middle East, and Europe, and was brought to the Americas by European colonizers in the 16th and 17th centuries. The name “coriander” derives from the Greek “koris,” meaning bedbug, a reference to the smell of the unripe leaves.

Varieties and aliases

  • Cilantro: The fresh leaves, used extensively in Mexican, Latin American, South Asian, and Southeast Asian cuisines.
  • Chinese parsley: An English name for the fresh leaves, common in Chinese culinary contexts.
  • Dhania: The Hindi and Urdu name for both the seeds and leaves, used across South Asia.
  • Coriander seed: The dried fruit of the plant, used whole or ground as a spice.
  • Vietnamese coriander (rau răm): A different species (Persicaria odorata) with a similar pungent, peppery flavor, used in Vietnamese cuisine as a cilantro substitute or complement. (Note: This is not a true variety of Coriandrum sativum but an unrelated herb that serves a comparable role.)

Culinary uses

Coriander leaves are almost always used fresh, added raw or at the very end of cooking to preserve their flavor. They are a defining garnish in Mexican salsas, tacos, and guacamole; in Indian chutneys and raitas; in Vietnamese pho and bún bò Huế; and in Thai salads and curries. The seeds are toasted and ground for spice blends such as garam masala, baharat, advieh, and harissa, and are used whole in pickling, in Russian Borodinsky bread, and in Ethiopian berbere. The root is also used in Thai cuisine, pounded into curry pastes. Coriander pairs well with cumin, garlic, chili, citrus, and alliums.

Cross-cuisine context

Coriander is one of the most globally distributed herbs, with meaningful analogues in nearly every cuisine represented on the platform. In Mexican cuisine, cilantro is an essential fresh herb for salsas, tacos, and pozole, with no direct substitute. In Persian cuisine, ground coriander seed is a key component of advieh (spice blends for rice and stews) and appears in southern khoresh dishes like ghaliyeh mahi. In Arabic cuisine, coriander seed is used in baharat and in the takleya (garlic-coriander tempering) for molokhia. In Armenian cuisine, fresh cilantro is used heavily in lobio and as a garnish for meze, while coriander seed appears in spice blends. In Cambodian cuisine, sawtooth coriander (chi banla) serves a similar fresh-herb role but with a stronger, more persistent flavor. In Vietnamese cuisine, rau răm (a different species) is used as a cilantro-like herb for chicken rice and bún bò Huế. In Russian and Georgian cuisines, fresh cilantro (kinza) is a defining herb in kharcho, satsivi, and adjika, while coriander seed is used in Borodinsky bread. In Salvadoran cuisine, cilantro is a common fresh herb used as a garnish and in sauces, though specific traditional uses of coriander seed are less documented. In Korean cuisine, cilantro is not traditional but appears in modern fusion dishes; minari (water dropwort) is sometimes used as a fresh herb garnish with a similar function.

Notes for cooks

  • Fresh cilantro leaves are highly perishable. Store them with stems in a glass of water, covered loosely with a plastic bag, in the refrigerator for up to a week. Change the water every two days.
  • Coriander seeds lose potency quickly once ground. Toast whole seeds in a dry pan until fragrant, then grind as needed for the strongest flavor.
  • A significant portion of the population has a genetic variation (OR6A2 receptor) that makes cilantro taste like soap or metal. For these cooks, flat-leaf parsley or culantro (Eryngium foetidum) can serve as a substitute in many dishes.
