Is it cilantro or is it coriander?
Well, actually it’s both. Cilantro refers to the leaves of the plant, and coriander references the seeds. Also known as Chinese parsley, this herb is indeed a member of the parsley family. This gentle little herb with lacy, fern-like leaves is a social creature, requiring other plants growing around it to aid in holding it up on its spindly stems that can reach 2+ feet in height. Excellent companion plants are caraway, anise and dill.
An annual, it is best first planted in cool weather, in a moderately rich, slightly alkaline, well-drained soil; this native of Asia and the Mediterranean regions prefers full to partial sun. In ideal conditions, cilantro (leaves) will last about 8 to 10 weeks before flowering. To ensure such conditions (this herb is not a friend of weeds), mulch to keep the roots cool and weed-free.
Once the herb flowers, producing a delicate white-to-lavender display, seeds will form; harvest them immediately when the leaves and flowers turn brown, but before the seeds disperse. To do this, cut the entire plant and hang it to dry upside down in paper bags. Occasionally shake the bags to thresh the seeds, but be certain that they have fully dried; coriander seeds can be bitter if only partially dry.
Once you have harvested the dried seeds, roast them in a frying pan over low to medium heat, frequently shaking the pan. Cool, then crush with a mortar and pestle just before use; this will release the flavor-and the trademark lemon-scented odor. The wise herb gardener will retain some of the seeds prior to drying for replanting every few weeks to guarantee a continuous supply.
When picking fresh cilantro, choose the small, young leaves (which are the tastiest) and cut with the stems on. Rinse well, and place the bunch, stem ends down, in a small glass of water as if you were displaying flowers. Cover with a plastic bag, securing with a rubber band, and refrigerate. Change the water daily, and your cilantro will last much longer.
The citrusy tang of cilantro has become a popular addition to Mexican cuisine, while Chinese, Thai, and Indonesian cuisines use both cilantro and coriander. Thai curries incorporate the chopped leaves of cilantro, while Indian curry powders owe their aromatic quality to ground coriander.
Coriander has been found in Egyptian tombs dating back 3,000 years. The ancient Hebrews used cilantro root as the maror, or bitter herb, during the symbolic Passover Seder meal. The Roman conquests of Europe and Asia introduced the use of cilantro as an aphrodisiac in China during the Han dynasty (207 BC – 200 AD); such usage is mentioned in The Tales of the Arabian Nights. But most notably, the visions of sugar plums which danced in children’s heads on the night before Christmas, originally referred to sugar-coated coriander.
The seeds, when chewed, freshen one’s breath; the essential oil is considered an aid in improving memory; and because of cilantro’s powerful scent, it has a reputation for attracting beneficial insects and deterring harmful ones.
Whether you call it cilantro or coriander, the distinctive characteristics of this tiny miracle herb make it a must-have for any herb garden.
