Coriander vs. Cilantro: Understanding the Difference

Coriander and cilantro are terms that often confuse even seasoned cooks. Despite referring to the same plant, Coriandrum sativum, their usage, meaning, and application vary widely depending on geography and culinary traditions. This guide dives deep into the world of coriander and cilantro, dissecting their definitions, cultural differences, culinary applications, and health benefits.

The Basics: What Are Coriander and Cilantro?

Both coriander and cilantro come from the same plant, Coriandrum sativum. The difference lies in which part of the plant you’re referring to and where you are in the world.

In the United States and Canada:

• Cilantro refers to the fresh, green leaves and stems of the plant.
• Coriander refers to the seeds, which are dried and often ground into a spice.

In the UK, Australia, and much of Europe:

• The term coriander encompasses both the fresh leaves and the seeds.
• “Cilantro” is rarely used.

This regional distinction is the root of much confusion.
