Where the fresh cilantro plant is bright and lemony, coriander seed is somewhat citrusy while still pungent. The seed is found in dishes around the world, from Indian curries to American chilis, from Belgian beer to being one of the kind-of-secret ingredients in Coca-Cola. Ground coriander is versatile for its use in rubs, marinades, stews, and dressings. And if you taste soap when eating cilantro, don't worry—that flavor isn't present in the seeds.
