I’ve been doing a series about foods that built civilizations. In this episode, we are talking about the potato. It is difficult to imagine that thousands of years ago, people constructed large buildings, managed rivers, built monuments, and created art. We have glimpses of these civilizations through stories, archaeology, and the structures they left behind, but much of their history has been lost. Imagine, we don’t even know where Cleopatra or Alexander the Great are buried, yet we know their stories. As European powers conquered Indigenous peoples, their languages, cultures, and oral traditions were suppressed. When a language disappears, so are the stories preserved within it. Our clues come from archaeology when we uncover a monument, a building, or an ancient settlement. In the Andes, the potatoes they cultivated were not the Russets, Yukon Golds, or fingerlings you find in the store today. Different colors, shapes, and textures. Adapted to survive the elevations, temperatures, and growing conditions. Biodiversity protected their food supply against frost, disease, and changing environmental conditions. If one variety failed, another might survive. The ancient wisdom of diversity that Andean farmers developed over thousands of years was lost when the potato eventually reached Ireland.
Preserving Potatoes They even developed a method to freeze-dry the crop. They exposed the potatoes to repeated cycles of freezing and thawing. Then they pressed them and allowed them to dry. The result was called chuño. The freeze-dried potatoes could be stored for years. When rehydrated, they were used in soups and stews. I wonder if they ever thought about freeze-drying the coffee berry. Perhaps there was an ancient people called the Sanka.
Tiwanaku: Farming at the top of the world The civilization flourished for centuries before it declined around the end of the first millennium CE. Near Lake Titicaca, in what is now Bolivia, the Tiwanaku civilization developed an agricultural system that allowed people to grow food in one of the most challenging environments on Earth. This pre-Inca civilization had monumental stone buildings, elaborate sculpture, and an extensive network of agricultural settlements. Its buildings and agricultural remains are still there. These people had an advanced civilization before the Inca. It is amazing to think the Inca were not the first to build a sophisticated society in the Andes. They developed raised agricultural fields, known today as waru waru. Water-filled channels surround these elevated planting beds. The channels helped moderate temperature fluctuations, reducing the risk of frost damage to crops, while the raised beds improved drainage and growing conditions.
The Inca: An empire built on agriculture The Incas inherited thousands of years of agricultural knowledge The empire depended on the ability of crops to grow at different elevations. Food was collected, stored, and distributed throughout their kingdom. Potatoes were important in the highlands, while maize, quinoa, and other plants supported populations in different environments. Machu Picchu sits high in the Andes. Its buildings, terraces, and water systems demonstrate advanced engineering. It is on most travelers' bucket lists. When the Spanish arrived, they encountered an unfamiliar vegetable, a product of thousands of years of agricultural experimentation. They would carry that vegetable across the Atlantic.
The Irish Lumper: The Potato That Fed a Nation The most famous potato is the Irish Lumper. When the Lumper arrived in Ireland, it thrived, even in poor soil, and produced enough food to sustain a family on a small plot of land. The Irish Lumper was a large, knobby, rather homely potato with pale skin and yellowish flesh. It wasn't known for its flavor. Historical accounts describe it as watery, bland, and sometimes soapy. It produced enough yield to feed your family. Add a little milk or buttermilk, and you have a diet that could sust

With all the spices we have access to, it is amazing how bland recipes have become. I have many cookbooks, some from great chefs, television personalities, and friends. What I am always surprised by is how bland the food has become. People seem to think a bit of salt, pepper, maybe onions, and garlic provide the spices one needs. Perhaps it is because some associate spice with heat. Mostly because many have never experimented with some of those great warm spices available. A pinch of coriander, some freshly ground cumin, a little cardamom, or a touch of cinnamon can turn an ordinary dish into something remarkable. And the most astonishing part is that these spices financed voyages around the world, built cities, created fortunes, and caused people to kill one another. Without the spice trade, it is safe to say that the United States, as we know it, would be vastly different from what it is now. The money loaned to the United States, when we were a fledgling country, came from the wealthy spice merchants from what was considered one of the great hyperempires of the world, based in Amsterdam. But before we go to the birth of the United States, let me take you to the meatball.
Tea: The Drink That Built an Empire—and Helped Break One China had the tea. Britain had the appetite. John Hancock had a business to protect.
MesoAmerica and Chocolate In our series looking at foods that built civilizations, today we are going to stay in the Americas with chocolate. Chocolate has been used as currency, consumed by kings, incorporated into religious ceremonies, and prescribed as medicine. Today, it is a multibillion-dollar industry that wants you to believe that eating chocolate is an act of preventive cardiology. I mean, why not? They convinced us to give chocolate to people we love, eat it when we are happy, when we are sad, when only the dog understands us. Don’t feed chocolate to your dog. And we have done all this with a bitter seed that most of us would probably spit out if we tasted it straight from the tree.
In our series about foods that built civilization, we talked a lot about grains, from wheat to corn to rice. Today, we are taking you to the ocean, with the civilizations that salmon built. From California to the interior of Alaska, salmon, a staple, allowed people to settle into villages, develop complex social networks, art, and trade routes. Those trade routes are as large as the ones in the Mediterranean. Some tribes built communal homes and developed complex art and language. Some were Seafaring tribes with canoes up to 60 feet long that traveled across oceans. All because there was a fish that would return in large numbers to streams and rivers, reliably, predictably. So predictable, the people could build their lives around salmon runs. So much so that some built a calendar not only with lunar cycles, but also with the return of the salmon. Civilizations have always gathered around food and water. The Mediterranean connected people who grew wheat and olives, giving people time to make wine, mine copper, build ships, trade with their neighbors, and occasionally go to war with them. Asia had rice and grain near the great river systems. The reliable calories from rice and grains allowed villages to become cities and to travel by water to trade. Today we are going to my home, from the Ventura River in California to my home state of Alaska.
Corn, beans, and squash, the three sisters, were the Native Americans’ crop, providing a stable source of calories, protein, and farming from Canada through South America. They allowed civilization to go from a hunting people to those who built cities that rivaled Europe and pyramids equal to the marvels seen in Egypt. The rise of civilizations has a pattern: grow a stable crop that allows people to survive, and go from nomads to develop complex societies. In our series of foods that built civilizations, we turn to the Americas before Europeans arrived. Long before Europeans arrived, civilizations in the Americas had developed writing, calendars, monumental architecture, cities, trade networks, irrigation systems, pottery, and sophisticated agriculture. Corn, or maize, fed the Maya, Inca, and Aztec worlds. In what is now the American Southwest, Pueblo peoples built multi-story communities in the desert, while Mississippian societies built towns and enormous earthworks along the great river valleys.
