Lore & Background
Coriander is a soft plant growing to 50 cm tall, with variable leaves—broadly lobed at the base and feathery higher up. Its flowers are borne in small umbels, white or very pale pink, with asymmetrical petals. The fruit is a globular, dry schizocarp 3–5 mm in diameter. The essential oil from leaves and seeds contains linalool as the major constituent, accounting for its aroma and flavor. The species is native to the Mediterranean Basin, growing wild over a wide area of West Asia and Southern Europe, making its exact origin difficult to define. Some research suggests Israel and Portugal as possible locations. Desiccated mericarps found in Pre-Pottery Neolithic levels in Israel are among the oldest known coriander remains. The herb is mentioned in the Torah and was recovered from the tomb of Tutankhamen, indicating cultivation by ancient Egyptians. Coriander may have been cultivated in Greece since at least the second millennium BCE, as indicated by Linear B tablets from Pylos referring to its use in perfume manufacture.
Reader's Guide
Coriander's significance lies in its dual use as both a fresh herb (cilantro) and a dried spice (coriander seeds), integral to many world cuisines including Peruvian, Mexican, Indian, and Southeast Asian. Its flavor perception is notably influenced by genetics: the gene OR6A2, which encodes a receptor sensitive to aldehydes, causes some people to perceive a soapy or rotten taste, while others enjoy a fresh, citrus flavor. Studies show variation in preference among ethnic groups, with lower dislike rates in cuisines where coriander is popular. The plant's long history of cultivation is evidenced by archaeological finds in Israel, Egypt, and Greece, and its mention in ancient texts. All parts are edible, and the leaves are rich in vitamins A, C, and K. The seeds provide dietary fiber and minerals. Coriander's legacy includes its role in traditional medicine and its continued global culinary importance, with similar plants like culantro and Vietnamese coriander used in various regions.
Did You Know?

- About 80% of identical twins share the same preference for coriander, but fraternal twins agree only about half the time, suggesting a strong genetic component.
- The essential oil from coriander leaves and seeds contains linalool as the major constituent accounting for its aroma and flavor.
- Coriander mericarps were recovered from the tomb of Tutankhamen, indicating cultivation by ancient Egyptians.
Frequently Asked Questions
Who is Coriander?
Coriander (Coriandrum sativum) is an annual herb in the Apiaceae family, originally native to the Mediterranean Basin. It is one of the most universally used cooking herbs on Earth, prized for both its fresh leaves and its dried seeds.
What are Coriander's powers and role in the kitchen?
Its leaves—called cilantro in American English—bring a bright, citrusy lift to dishes, while the dried seeds contribute a warm, gently sweet note. It is a cornerstone ingredient in Peruvian, Mexican, Indian, and Southeast Asian cuisines.
Where does Coriander come from, and how old is it?
The plant is indigenous to the Mediterranean region and has been grown by humans for thousands of years, with archaeological specimens uncovered in Israel and Egypt. It spread across the globe through trade routes and agricultural expansion.
Why do some people swear Coriander tastes like soap?
A well-documented genetic variation causes certain individuals to perceive a soapy or metallic quality in the leaves rather than the typical fresh, citrusy flavor. This is a genuine difference in taste perception, not simply a matter of personal preference.
How does Coriander's story end?
As a true annual, the plant lives through germination, leafy growth, flowering, and seed production all within a single growing season before it dies back. Its dried seeds, however, preserve the flavor for the next year's harvest and beyond.
