Article Summary
What this article covers: The spice trails, the sea and land routes that carried pepper, cloves, nutmeg and cinnamon from Asia to Europe, and where those flavours still turn up, from Kerala to Cork.
Who this is for: Food-curious travellers, history readers, and anyone who has wondered why an Irish Christmas smells of cloves.
Key takeaway: Most of the spices in a Western kitchen cupboard came from a handful of specific places, and you can still visit nearly all of them.
Expert insight: “In a Kochi spice warehouse, the pepper reaches you before your eyes adjust to the dark. Then you’re in Cork’s English Market at Christmas, you catch the clove in a slab of spiced beef, and it clicks: it’s the same trade, just the other end of it.”- Ciaran Connolly, Founder of ConnollyCove.
Quick facts:
- Nutmeg and mace come from the same tree, which is native only to Indonesia’s Banda Islands.
- Vasco da Gama reached Calicut, on India’s Malabar Coast, by sea in 1498.
- Chillies come from the Americas. They only reached Indian and Thai kitchens in the sixteenth century.
The spice trails were never a single road. They were a loose web of monsoon sea lanes, caravan tracks and harbour towns that moved pepper, cloves and cinnamon west from Asia. Every spice changed hands several times, and every merchant added his cut. Some cargo joined the overland caravans covered in our guide to trade and culture on the Silk Road, but most of it went by sea.
Ireland sits at the far end of that chain, which is why ConnollyCove, an Ireland-based travel and culture platform, keeps coming back to it. A slice of barmbrack or a round of Cork spiced beef is the last stop on a route that began thousands of miles east. Here’s where those flavours started, who fought over them, and where you can still taste them.

What Were the Spice Trails?
The spice trails linked the growing regions of South and Southeast Asia with the Middle East, East Africa and Europe. Most spices went by ship. Traders used the monsoon winds to cross the Indian Ocean, then sailed up the Red Sea or the Persian Gulf towards Alexandria and the Levant. In the medieval period, Venetian merchants bought spices in those ports and sold them across Europe at a heavy markup.
That long relay explains the prices. By the time pepper reached a kitchen in London or Dublin, it had passed through five or six sets of hands.
| Spice | Native region | Historic trade hub | Where to taste it today |
|---|---|---|---|
| Black pepper | Malabar Coast, Kerala | Muziris, Calicut | Keralan fish curries |
| Cloves | North Moluccas, Indonesia | Ternate, Malacca | Zanzibari pilau, Irish Christmas baking |
| Nutmeg and mace | Banda Islands, Indonesia | Banda Neira, Amsterdam | Barmbrack, mince pies |
| True cinnamon | Sri Lanka | Galle, Colombo | Sri Lankan curries and sweets |
| Cardamom | Western Ghats, India | Calicut | Masala chai, Scandinavian buns |
Where Did the Flavours Come From?
Nearly every classic spice traces back to a surprisingly small patch of ground. The trade was so valuable partly because the supply was so concentrated.
Pepper grows as a climbing vine in the hills behind India’s Malabar Coast, in what is now Kerala. Green, black and white pepper all come from the same berry. Black pepper is the unripe fruit dried in the sun, and white pepper is the ripe fruit with its skin removed. Roman ships once sailed to the port of Muziris to buy it.
Cloves are dried flower buds from the Moluccas in eastern Indonesia. Nutmeg is a seed from the Banda Islands, wrapped in a lacy red covering that is sold separately as mace. For centuries, no other place on Earth produced them.
Cinnamon is the inner bark of a Sri Lankan tree, peeled and rolled into thin quills. You’ll find the colonial port of Galle in our guide to things to do in Sri Lanka. Much of the “cinnamon” sold in supermarkets is actually cassia, a close relative from China and Southeast Asia. Cassia is thicker and harsher, and it contains far more coumarin.
Zanzibar came later. Cloves were planted there under Omani rule in the nineteenth century, largely by enslaved workers. The island’s older monsoon trading links are covered in our piece on Indian Ocean island cultures.
Who Controlled the Spice Trade?
Whoever controlled the supply controlled the money. For centuries that meant Arab, Persian and Gujarati merchants, with Venice acting as Europe’s broker. Portugal broke that hold when Vasco da Gama sailed around Africa and reached Calicut in 1498. Lisbon then became Europe’s pepper market.
The Dutch East India Company (the VOC), founded in 1602, went further. It seized the Banda Islands by force in 1621, killing or enslaving much of the local population so it could monopolise nutmeg. Under the Treaty of Breda in 1667, the Dutch kept the tiny nutmeg island of Run and the English kept New Amsterdam, now Manhattan.
That’s the uncomfortable side of the story, and it belongs in any honest account. ConnollyCove’s guide to the Age of Exploration covers the wider cost of those voyages.
Why Were There No Chillies on the Old Spice Trails?
Chillies are American. Before the sixteenth century, the heat in Indian cooking came from black pepper and long pepper, and Thai cooks relied on pepper and ginger. Portuguese traders brought capsicums from the Americas to Goa, and from there they spread across Asia within a few generations.
The spice trade kept producing new dishes like this. British cooks in India invented mulligatawny and kedgeree. Chinese migrants to Peru created chifa, which combines soy sauce and ginger with Andean ingredients. The chilli-heavy stalls in our street food guide to Bangkok, Mexico City and Marrakech show how fully those later arrivals took over.
How Did the Spice Trails Shape Irish Food?
Ireland rarely appears in spice-trade histories, yet its festive food depends on imported spices. The clearest example is Cork spiced beef. Beef is cured for days or weeks in salt, sugar, and a spice mix, and butchers’ recipes are often family secrets. Cork was a major port for supplying Atlantic ships, and curing meat with salt and spice helped it keep. The Irish Times has profiled English Market butchers who brought spiced beef back from near-disappearance. James Joyce even puts a “round of spiced beef” on the Christmas table in The Dead.
Barmbrack tells a similar story. The Halloween loaf gets its warmth from mixed spice, a blend that usually contains cinnamon, nutmeg and cloves, along with allspice from the Caribbean. Our guides to traditional Irish food and seasonal foods in Irish folklore trace how those dishes settled into the Irish calendar. The charm-in-the-brack custom itself goes back to Samhain.
Barmbrack ties Ireland to two trade networks. The Banda Islands supplied the nutmeg, and the Atlantic trade supplied the allspice.
How Can You Follow the Spice Trails Today?
You can walk most of the old routes in person, and the smells haven’t moved. Start in Kochi, Kerala, where the old warehouses of Mattancherry still sort and sell pepper and ginger. Kerala is also one of the better-value regions in our list of cheapest travel destinations.
Zanzibar’s spice farms near Stone Town run guided walks where you can taste cloves, nutmeg and cinnamon straight from the plant. In Sri Lanka, Galle Fort shows both the Portuguese and Dutch periods in its stonework. Istanbul’s Spice Bazaar and the souks of Marrakech are the loudest reminders of the old middlemen, and our guide to Middle Eastern souks and spice markets covers what to expect.
End at home. Cork’s English Market has traded since the late eighteenth century, and December is the time to go.
One practical tip: buy whole spices and grind them yourself. Look for Ceylon quills that crumble between your fingers, not hard cassia sticks.

FAQs About the Spice Trails
These are the questions travellers ask most often about the spice trails. The answers are kept short so you can find what you need quickly.
What is the difference between the Spice Route and the Silk Road?
The Silk Road ran mainly overland across Central Asia. The spice routes were mostly sea lanes across the Indian Ocean.
Which spices came from the Spice Islands?
Cloves, nutmeg and mace. All three grew natively only in Indonesia’s Moluccas.
Why was black pepper so expensive in Europe?
It passed through many traders, and each one added a markup. It also stored well, which made it a reliable way to hold value.
Who first reached India by sea from Europe?
Vasco da Gama, who landed near Calicut in 1498.
How can you tell Ceylon cinnamon from cassia?
Ceylon cinnamon is made of thin, papery layers rolled like a cigar. Cassia is a single thick, hard curl.
Did the spice trade change Irish food?
Yes. Cork spiced beef and barmbrack both depend on spices brought in by sea.
