Understanding the terminology around this popular herb clears up frequent confusion in kitchens worldwide. The distinction between cilantro and coriander isn't about different plants—it's about regional naming conventions and which part of the plant people are referring to.
Why Two Names for the Same Plant?
The dual naming system stems from linguistic evolution and geographical differences. The word "cilantro" comes from Spanish, which itself derived from the Latin coriandrum. In most Spanish-speaking countries and throughout the Americas, "cilantro" specifically means the fresh leaves.
Meanwhile, "coriander" is the term preferred in British English and throughout most of the world. This broader term refers to the entire plant—both the fresh leaves (what Americans call cilantro) and the dried seeds.
| Term Used | Refers To | Common Regions |
|---|---|---|
| Cilantro | Fresh leaves and stems | United States, Canada, Latin America |
| Coriander (leaves) | Fresh leaves and stems | United Kingdom, Australia, Asia, Africa |
| Coriander (seeds) | Dried seeds | Worldwide |
Botanical Background of Coriandrum sativum
The cilantro/coriander plant (Coriandrum sativum) belongs to the Apiaceae family, which includes parsley, carrots, and celery. This annual herb grows to about 50 cm tall with slender stems and variable leaf shapes—broad and lobed at the base, finely divided higher up.
What many don't realize is that both terms describe parts of the exact same plant. When you see "coriander" on a seed packet outside North America, it likely contains the same seeds that will grow what Americans call "cilantro" plants.
Regional Terminology Differences Explained
Understanding where each term predominates helps avoid confusion in international recipes and cooking discussions:
- North America: "Cilantro" = fresh leaves; "Coriander" = dried seeds
- United Kingdom & Commonwealth: "Coriander" = both fresh leaves and seeds (often specified as "fresh coriander" or "coriander seeds")
- Asia: Local names vary, but "coriander" is commonly understood for both forms
- Spain & Latin America: "Cilantro" = fresh leaves; "Coriandro" or "Cilantro en grano" = seeds
This explains why searching for another name for cilantro in the UK yields "coriander" as the primary answer, while Americans might be confused when British recipes call for "coriander" when they mean the fresh herb.
Culinary Applications: Leaves vs. Seeds
The different parts of the plant serve distinct culinary purposes, which partly explains the naming distinction:
| Plant Part | Flavor Profile | Common Culinary Uses |
|---|---|---|
| Fresh leaves (Cilantro) | Bright, citrusy, sometimes described as soapy (for some) | Salsas, guacamole, garnishes, Southeast Asian soups, chutneys |
| Dried seeds (Coriander) | Warm, nutty, citrus undertones | Curry powders, pickling spices, baked goods, meat rubs |
| Roots | More intense, earthy version of leaf flavor | Thai curry pastes, soups (often pounded into pastes) |
Addressing Common Misconceptions
One widespread misunderstanding is that cilantro and coriander are different plants. They're not—they're simply different parts of Coriandrum sativum. Another common point of confusion involves the "cilantro soap taste" phenomenon.
When people say they taste soap when eating cilantro, they're referring specifically to the fresh leaves—not the seeds. This genetic trait affects about 21% of the population and relates to olfactory-receptor genes that interpret certain aldehydes in cilantro as soapy.
Understanding what is cilantro called in other countries prevents recipe mishaps. If you're following a British cookbook that calls for "coriander" in a fresh herb context, they mean what Americans would call cilantro.
Practical Tips for Using Cilantro/Coriander
Whether you call it cilantro or coriander, here's how to maximize its culinary potential:
- Selection: Choose vibrant green bunches with no yellowing. Stems should be crisp, not slimy.
- Storage: Trim stems, place in water like flowers, cover loosely with plastic bag, and refrigerate. Change water every 2-3 days.
- Freezing: Chop leaves, place in ice cube trays with water or oil, and freeze for long-term storage.
- Seed Toasting: Lightly toast coriander seeds before grinding to enhance their warm, citrusy flavor.
- Substitutions: If you dislike cilantro's flavor, try flat-leaf parsley with a squeeze of lime for similar texture and brightness.
When exploring the difference between cilantro and coriander, remember that context matters most. In international cooking communities, understanding these naming conventions prevents confusion and expands your culinary repertoire.
