Coriander seed is the cocktail spice most drinkers consume daily without knowing. Every London Dry gin has it. Often the second-largest botanical by volume. The lemon-pepper-floral character it adds is part of what makes gin taste like gin. Used directly in cocktails (syrup, infusion, garnish), it gives drinks a quietly sophisticated lift.

What it is

Coriandrum sativum. The dried, ripe seed of the coriander plant (whose leaves are cilantro). Despite both being from the same plant, the leaf and seed taste completely different. Native to the Mediterranean and Middle East, grown globally.

Flavour profile

Citrus-pepper, slightly floral, with a faintly nutty-sweet underbelly. The aroma is gentle until crushed; then it opens up dramatically. Pairs naturally with gin, bourbon, rum, brandy. Companion ingredients: citrus (especially lemon and orange), cardamom, ginger, fennel, anise, juniper.

Where to source coriander seed in Malaysia

Indian groceries: the best source. RM 10 to 20 per 100g jar. Always sold whole.

Supermarkets: any Malaysian supermarket in the spice aisle. Whole or pre-ground.

Quality marker: whole seeds should be plump and aromatic when crushed. Pre-ground loses character within weeks; always buy whole and crush as needed.

How to prep coriander seed for cocktails

Lightly crushed in shaker. 1 teaspoon whole seeds, lightly crushed in a mortar, dropped into the shaker before adding ice. Strain out. The cocktail picks up the floral-pepper character.

Coriander syrup. 1 tablespoon lightly crushed seeds + 250ml water + 200g sugar. Simmer 10 minutes, steep covered 30 minutes, strain. Keeps refrigerated 3 weeks.

Coriander-citrus tincture. 30g lightly crushed seeds + zest of 2 oranges + 200ml vodka. Steep 2 weeks. Strain. Use 2-3 dashes per cocktail.

Coriander-infused gin. Already in your gin, but you can amplify: 1 tablespoon crushed seeds in 500ml gin, leave 12 hours, strain. The gin becomes more juniper-coriander forward.

Best cocktails with coriander seed

Coriander Gin and Tonic: gin, tonic, ice, half-teaspoon lightly crushed coriander seeds in the glass.

Coriander Margarita: tequila, fresh lime, triple sec, coriander syrup.

Orange-Coriander Old Fashioned: bourbon, coriander syrup, orange bitters.

Citrus Coriander Highball: vodka or gin, fresh lemon, coriander syrup, soda.

In Malaysian use

Coriander seed (ketumbar in Malay) is not native to Malaysia (it originates in the Mediterranean and Middle East) but has been here long enough through Indian and Arab trade routes to become a foundational spice in local cooking. It is one of the four pillars of Malaysian curry powder (alongside cumin, fennel, and turmeric), and it appears in nasi minyak, beef rendang, kari ayam, beriani, mutton soup, and most mamak-style preparations. Whole seeds are also dry-toasted and ground for rempah pastes across Malay, Peranakan, and Indian-Muslim kitchens.

For sourcing, the best whole coriander seed is at the Brickfields Indian grocers along Jalan Tun Sambanthan and the spice stalls at Pudu and Chow Kit markets, at RM 8 to 18 per 100g. Most supermarkets also carry it, sometimes pre-ground at slightly inflated prices. At the bar we sometimes pair lightly crushed ketumbar with calamansi and gin for an aromatic gimlet that pulls on the same spice the rendang in the kitchen does, an unusual link between the dinner and the drink that local guests catch immediately.

Substitutions

  • Cardamom for the warm-aromatic direction.
  • Lemon zest for the citrus-pepper character (less complex).
  • Fennel seed for an anise-floral alternative.

Frequently asked questions

What does coriander seed taste like in cocktails?

Coriander seed is citrus-pepper with a faintly floral and nutty-sweet underbelly. The aroma is gentle until crushed, then opens up dramatically. It is the second-largest botanical in most London Dry gins and is part of what makes gin taste like gin. Pairs naturally with gin, bourbon, rum, brandy, lemon, orange, cardamom, ginger, and juniper.

Where can I buy coriander seed in Malaysia?

The Brickfields Indian grocers along Jalan Tun Sambanthan have the best whole coriander seed at RM 8 to 18 per 100g. The spice stalls at Pudu and Chow Kit markets also stock it. Most supermarkets (Aeon, Cold Storage, Village Grocer) carry whole and pre-ground in the spice aisle. Always buy whole; pre-ground loses character within weeks.

What can I substitute for coriander seed?

Cardamom covers the warm-aromatic direction but is more eucalyptus. Lemon zest gives the citrus-pepper character but lacks the floral complexity. Fennel seed works as an anise-floral alternative. None replicate coriander seed's specific lemon-pepper-floral chord; this is the spice that anchors gin for a reason.

Which cocktails use coriander seed?

Coriander Gin and Tonic (with half-teaspoon crushed seeds in the glass), Coriander Margarita, Orange-Coriander Old Fashioned, and the Citrus Coriander Highball. At our bar, we sometimes pair lightly crushed ketumbar with calamansi and gin for an aromatic gimlet that pulls on the same spice the rendang in the kitchen does.

How long does coriander seed keep?

Whole coriander seeds keep 2 to 3 years in an airtight jar in a cool dark cupboard. Crushed coriander loses most of its aroma within 1 to 2 months. Coriander syrup keeps 3 weeks refrigerated. Coriander-citrus tincture is shelf-stable indefinitely. Coriander-infused gin lasts 6 months in a sealed bottle.
