Coriander seed
kor-ee-AN-der
Coriandrum sativum
Citrusy, floral, warm, lightly sweet.
What it is
Coriander seed is the dried fruit of Coriandrum sativum, the same plant whose leaves are sold as cilantro. The round, ridged seeds taste nothing like the leaves: where cilantro is green and soapy to some, the seed is warm, citrusy, and gently sweet, with a floral note that toasting brings forward. It is a base spice across Indian, Middle Eastern, North African, and Thai cooking, often paired with cumin in roughly equal parts. Ground coriander also acts as a mild thickener and binder in spice pastes and curries.

What it pairs with
Goes wrong with: very delicate broths.
Common in Indian, Middle Eastern, Thai, Moroccan cooking.
Whole vs ground
Whole seeds are mild and easy to toast for a citrus lift. Ground coriander loses its top notes within a few months, so grind small amounts from whole when you can.
How to handle it
Toast whole seeds briefly, then crush. They crack easily, which makes coriander one of the friendliest spices to grind by hand in a mortar.
Storage
Airtight and dark. Whole seeds last well over a year; ground fades within four months.
Buying note
Look for pale, round, evenly colored seeds. They should smell bright and orange-like when you crush one.
Classic dishes
garam masala, harissa, dukkah, Thai curry paste.
Out of coriander seed? Substitutes
No substitute is exact. These are the closest by flavor behavior, with the ratio to start from and how the result will differ.
| Use instead | Ratio | How it differs |
|---|---|---|
| Ground cumin | use about half | earthier and heavier, loses the citrus lift |
| caraway plus a little fennel | 1:1 combined | more aniseed, less orange-citrus |
One odd thing
Coriander seeds were found in the tomb of Tutankhamun, and the plant rarely grows wild, which suggests it was one of the earliest spices people deliberately cultivated.
