How spices shaped the world
Open your spice rack and you're looking at a map of world history. For most of recorded time, a handful of dried seeds, barks and berries were worth fighting wars over.
Pepper: the spice that paid for empires
Black pepper grows on vines along the Malabar coast of southwest India. Ancient Rome imported so much of it that Roman writers complained about the gold flowing east to pay for it. Pepper stayed one of the most traded goods on earth for well over a thousand years.
Nutmeg: one tiny group of islands
Until the 1700s, nutmeg and mace grew only on the Banda Islands in what is now eastern Indonesia. Whoever controlled those few islands controlled the world's supply. In 1621 the Dutch East India Company seized the Bandas by force, killing or enslaving much of the population, so it could own the trade. It's one of the darkest chapters behind an everyday spice.
Sailing for spices
The search for a sea route to the spice lands drove the age of exploration. Vasco da Gama reached India by sailing around Africa in 1498. Columbus sailed west in 1492 trying to reach the spice markets of Asia, and landed in the Americas instead.
Chili: the plot twist
Here's the part that surprises people: chili peppers come from the Americas. Before the 1500s there was no chili heat in Indian curries, Thai food, Sichuan cooking or Korean kimchi. After Columbus, traders carried chilies across Africa and Asia, and within a century or two whole cuisines were built around them.
Cinnamon and the ones that stayed close to home
True cinnamon comes from the inner bark of a tree native to Sri Lanka. Ginger and turmeric come from South and Southeast Asia, vanilla from Mexico, allspice from the Caribbean. Every one of them changed hands many times before it reached a kitchen.
Try it: make one dish twice, once with pre-1492 spices only (pepper, ginger, cinnamon) and once with chili. Taste the history.
