Cilantro and coriander: two words that often cause confusion in the kitchen and beyond. Are they the same thing? Are they different plants entirely? The answer, while simple, requires a bit of botanical and culinary exploration. In short, cilantro and coriander refer to the same plant, Coriandrum sativum, but different parts of it. Cilantro refers to the leaves and stems, while coriander refers to the seeds. This distinction, however, varies geographically, adding another layer of complexity to the discussion.
The Botanical Background: *Coriandrum sativum*
To understand the cilantro-coriander conundrum, it’s essential to start with the botanical foundation. Coriandrum sativum is an annual herb belonging to the Apiaceae family, which also includes parsley, carrots, and celery. Native to the Mediterranean region, the plant has been cultivated for thousands of years, with evidence of its use dating back to ancient Egypt.
The plant itself is relatively small, typically growing to a height of about 50 centimeters (20 inches). It features delicate, feathery leaves that are responsible for the cilantro flavor. When the plant matures, it produces small, round seeds, which are known as coriander seeds. These seeds have a distinct flavor profile, vastly different from the fresh leaves.
The entire plant is edible, but the leaves and seeds are the most commonly used parts in cooking. While the roots are sometimes used in Southeast Asian cuisine, they are less widely available and appreciated in other parts of the world.
Regional Variations: A Matter of Terminology
The main source of confusion stems from regional variations in terminology. In North America, “cilantro” refers specifically to the leaves and stems of the Coriandrum sativum plant. The seeds, on the other hand, are always called “coriander.”
In other parts of the world, particularly in the United Kingdom, Australia, and India, the term “coriander” is used more broadly to refer to the entire plant, including both the leaves and the seeds. To avoid ambiguity, the leaves are sometimes called “coriander leaves” or “fresh coriander.” This broader usage can lead to misunderstandings, especially when following recipes or discussing culinary preferences.
The following table summarizes the regional differences:
| Region | Leaves & Stems | Seeds |
|---|---|---|
| North America | Cilantro | Coriander |
| United Kingdom, Australia, India | Coriander (or Coriander Leaves/Fresh Coriander) | Coriander |
This difference in nomenclature is crucial to keep in mind when communicating about this versatile herb. Knowing where someone is from can often clarify their intended meaning.
The Flavor Profile: A Tale of Two Tastes
Perhaps the most striking difference between cilantro and coriander lies in their flavor profiles. While they both come from the same plant, the leaves and seeds possess drastically different tastes.
Cilantro, the fresh leaves and stems, is known for its bright, citrusy, and slightly peppery flavor. It adds a refreshing element to dishes and is often used as a garnish or ingredient in salsas, salads, and Asian-inspired cuisine. However, cilantro is also notorious for its polarizing effect on taste buds. Some people perceive it as having a pleasant, citrusy flavor, while others find it soapy or even offensive.
This difference in perception is largely attributed to genetics. A specific gene, OR6A2, is responsible for detecting aldehydes, which are organic compounds found in cilantro. People with a variation of this gene are more likely to perceive the soapy flavor in cilantro. This genetic predisposition explains why some individuals love cilantro while others despise it.
Coriander seeds, on the other hand, have a warm, nutty, and slightly citrusy flavor. They are often described as having a more mellow and rounded taste compared to the sharp, pungent flavor of cilantro. Coriander seeds are used as a spice in a wide range of cuisines, including Indian, Middle Eastern, and Mediterranean. They can be used whole, ground, or toasted to enhance their flavor.
The difference in flavor is due to different volatile compounds present in the leaves and seeds. Cilantro contains a higher concentration of aldehydes, which contribute to its characteristic flavor and the soapy perception in some individuals. Coriander seeds contain different compounds, such as linalool and pinene, which contribute to their warm and nutty flavor.
Culinary Uses: Versatility in the Kitchen
Both cilantro and coriander are highly versatile ingredients that can be used in a wide range of dishes. Their distinct flavor profiles make them suitable for different culinary applications.
Cilantro: A Fresh Herb for Flavor and Garnishing
Cilantro is primarily used as a fresh herb to add flavor and aroma to dishes. Its bright, citrusy flavor complements a variety of cuisines, particularly those from Latin America and Asia.
Some popular uses for cilantro include:

- Soups and Stews: Cilantro can be used as a garnish for soups and stews, adding a refreshing touch.
- Asian Cuisine: Cilantro is widely used in Southeast Asian cuisine, particularly in Vietnamese and Thai dishes.
Cilantro is best added towards the end of cooking, as its flavor can diminish with prolonged heat exposure. It is also important to wash cilantro thoroughly before use to remove any dirt or debris.
Coriander Seeds: A Spice for Depth and Warmth
Coriander seeds are used as a spice to add depth and warmth to dishes. Their nutty and slightly citrusy flavor complements a variety of cuisines, including Indian, Middle Eastern, and Mediterranean.
Some popular uses for coriander seeds include:
- Curries: Coriander seeds are a key ingredient in many Indian curries, adding a warm and aromatic flavor.

- Baking: Coriander seeds can be used in baking, particularly in breads and pastries.
- Meat Rubs: Ground coriander seeds can be used as a component of dry rubs for meats prior to cooking.
Coriander seeds can be used whole, ground, or toasted. Toasting the seeds before grinding them enhances their flavor and aroma. Ground coriander seeds should be stored in an airtight container in a cool, dark place to preserve their flavor.
Nutritional Value: A Source of Vitamins and Minerals
Both cilantro and coriander seeds offer nutritional benefits, although their nutritional profiles differ slightly.
Cilantro is a good source of vitamins A, C, and K, as well as folate and potassium. It also contains antioxidants, which can help protect against cell damage.
Coriander seeds are a good source of dietary fiber, manganese, and iron. They also contain antioxidants and have been shown to have anti-inflammatory properties.
Incorporating both cilantro and coriander seeds into your diet can contribute to overall health and well-being.
Cultivation and Storage: Growing Your Own and Keeping it Fresh
Coriandrum sativum is relatively easy to grow, making it a popular choice for home gardeners. Both cilantro and coriander seeds can be cultivated in a variety of climates.
Cilantro prefers cool weather and well-drained soil. It can be grown from seed or seedlings. Regular harvesting of the leaves will encourage continued growth. However, cilantro has a tendency to bolt (flower) in hot weather, which can make the leaves bitter.
Coriander seeds are harvested from the mature plant after the flowers have faded and the seeds have turned brown. The seeds can be dried and stored in an airtight container.
To keep cilantro fresh after harvesting, it should be stored in the refrigerator. One method is to trim the stems and place the cilantro in a glass of water, covering the leaves loosely with a plastic bag. This will help keep the cilantro hydrated and prevent it from wilting.
Conclusion: Appreciating the Duality of *Coriandrum sativum*
In conclusion, while the terms “cilantro” and “coriander” may seem confusing, they simply refer to different parts of the same plant, Coriandrum sativum. Cilantro refers to the leaves and stems, while coriander refers to the seeds. This distinction is particularly important to understand in North America, where these terms are used consistently. In other regions, such as the United Kingdom and Australia, “coriander” may be used to refer to the entire plant.
By understanding the botanical background, regional variations, flavor profiles, culinary uses, and nutritional value of both cilantro and coriander, you can appreciate the versatility of this remarkable herb and use it to enhance your culinary creations. Whether you love the bright, citrusy flavor of cilantro or the warm, nutty flavor of coriander seeds, there’s a place for both in your kitchen.
What is the difference between cilantro and coriander?
The terms cilantro and coriander actually refer to the same plant, Coriandrum sativum. “Cilantro” is the name used for the fresh leaves of the plant, while “coriander” refers to the dried seeds. This difference in nomenclature is primarily geographical, with “cilantro” being more common in North America, and “coriander” used more widely in Europe, Asia, and other parts of the world.
Therefore, the difference is not about distinct varieties or species, but rather which part of the Coriandrum sativum plant you are using. Understanding this distinction is crucial for avoiding confusion when following recipes or discussing culinary preferences. In essence, cilantro leaves and coriander seeds are two distinct ingredients derived from the same source.
Why do some people dislike the taste of cilantro so much?
The intense dislike some people experience towards cilantro is largely attributed to a genetic predisposition. A specific gene, OR6A2, plays a role in detecting aldehydes, a type of organic compound found in cilantro. Individuals with a particular variant of this gene are more sensitive to these aldehydes, which are also found in soap, leading them to perceive cilantro as having a soapy or unpleasant flavor.
This genetic factor isn’t the only influence; cultural exposure and learned preferences also contribute to taste perception. People who grow up frequently consuming cilantro are less likely to find its taste offensive, regardless of their genetic makeup. Therefore, while genetics play a significant role, it’s not the sole determinant of cilantro aversion.
What are the culinary uses of cilantro?
Cilantro, with its bright, citrusy, and slightly peppery flavor, is widely used as a fresh herb in numerous cuisines. It’s a staple ingredient in Mexican dishes like salsa, guacamole, and tacos, adding a refreshing element that balances rich and spicy flavors. It is also used extensively in Southeast Asian cuisine, including Vietnamese pho and Thai curries, where it contributes a distinct aromatic character.
Beyond these regional specialties, cilantro can be incorporated into salads, used as a garnish for soups and stews, or blended into sauces and marinades. Its delicate leaves are best added at the end of cooking to preserve their fresh flavor and vibrant green color. However, some cooks might add the stems to stocks and broths for an extra depth of flavor.
How do you store cilantro to keep it fresh longer?
Proper storage is essential to prolong the freshness of cilantro. One effective method involves trimming the stems and placing the bunch in a jar or glass filled with about an inch of water, similar to how you would treat cut flowers. Then, loosely cover the cilantro with a plastic bag and store it in the refrigerator.
Another approach is to wrap the cilantro in a slightly damp paper towel before placing it in a plastic bag. This helps maintain humidity without causing the leaves to become soggy. Change the water every few days (if using the jar method) and remove any yellowing or wilting leaves to prevent them from affecting the rest of the bunch. Stored properly, cilantro can last for up to a week or more in the refrigerator.
What are the health benefits of coriander seeds?
Coriander seeds are rich in antioxidants, which help protect the body against cellular damage caused by free radicals. These antioxidants contribute to overall health and well-being by reducing the risk of chronic diseases. Furthermore, coriander seeds have been shown to have anti-inflammatory properties, potentially alleviating symptoms of conditions like arthritis.
Beyond antioxidants, coriander seeds are a good source of dietary fiber, which aids in digestion and helps regulate blood sugar levels. They also contain essential vitamins and minerals, including vitamin C, vitamin K, and potassium, contributing to various bodily functions. Some studies suggest that coriander seeds may also have antimicrobial properties, helping to fight against certain bacteria and fungi.
Can coriander seeds be substituted for cilantro, or vice versa?
Substituting coriander seeds for cilantro, or vice versa, is generally not recommended due to their significantly different flavor profiles and textures. Cilantro provides a fresh, herbaceous, and slightly citrusy flavor that is quite distinct from the warm, earthy, and citrusy notes of coriander seeds. The texture is also vastly different; cilantro is a leafy herb, while coriander seeds are dried and have a more granular consistency.
While both come from the same plant, their culinary roles are often distinct. In recipes that call for cilantro, a suitable substitute might be parsley or Mexican oregano, depending on the specific dish. For coriander seeds, cumin or caraway seeds could offer a similar warm, earthy flavor in a pinch, but they won’t replicate the exact taste. Thus, a direct substitution is not ideal.
How are coriander seeds typically used in cooking?
Coriander seeds are used extensively in both whole and ground forms in a wide variety of cuisines. Whole coriander seeds are often toasted to enhance their aroma and flavor before being added to curries, stews, and pickling brines. Toasting brings out the essential oils and adds depth to the overall dish. They are also commonly used in spice blends like garam masala.
Ground coriander is a popular spice in baking and is often included in spice rubs for meats and vegetables. Its warm, citrusy flavor pairs well with both sweet and savory dishes. It is commonly found in baked goods, such as gingerbread and spice cakes, as well as in rubs for grilled chicken and fish. The versatility of coriander seeds makes them a valuable addition to any spice rack.
