48:19Every second of every day, plants on earth do something miraculous: they take the carbon dioxide from air and turn it into food. With very few exceptions, everything we eat starts out that way. But what if we wanted to cut out the middlemen, re-wild all those fields full of wheat and corn, and manufacture dinner directly from the atmosphere ourselv…

At last, an episode on pizza! But that raises a tricky question: what exactly is pizza? As it turns out, the original pizzas from eighteenth-century Naples looked nothing like a standard slice—they were more like a focaccia, topped with oil, herbs, anchovies, or whatever else was on hand. Even after these first pizzas met the tomato, the dish was a…

Whether or not it's Tuesday, tacos pretty much always hit the spot—and not just in their homeland in Mexico. These days, the taco can be found all over the world, although it's acquired some strange new fillings along the way, from French fries to canned corn. It's hard to imagine something so universal having to be invented—but, in fact, the taco …

The tomato is Gastropod’s favorite flavor of summer, and we’re not alone: today, it’s the most popular vegetable on the planet, despite the fact that it's technically a fruit. But, until a couple of hundred years ago, the tomato wasn't really anyone's favorite. In South America, where the tomato originates, no one even bothered to domesticate it; i…

It's the epitome of summertime: there’s nothing like a cold, juicy slice of red watermelon on a swelteringly hot day. But, once upon a time, watermelons were neither red nor sweet—the wild watermelon has white flesh and a bitter taste. This episode, we scour Egyptian tombs, decaying DNA, and ancient literature in search of watermelon's origins. The…

We rely on corn—globally, more maize is grown than wheat or rice—and, in turn, corn is utterly dependent on us, to the extent that it's lost the ability to reproduce without our help. But corn's wild ancestor is such an unappetizing weed that, for decades, archaeo…
