Tomatoes arrived in Europe from the Americas in the 1500s and were regarded with suspicion in many regions for generations. They belong to the nightshade family, which includes genuinely poisonous plants like mandrake and deadly nightshade, already associated with poisons and witchcraft. The name lycopersicon, meaning wolf’s peach, was not invented because Europeans feared red tomatoes. It was an ancient Greek term attached to a different plant centuries earlier, which Renaissance botanists applied to the tomato while trying to match newly discovered plants to descriptions in classical texts. Meanwhile, in southern Europe, cooks were already using tomatoes and developing the first surviving European tomato sauce recipes.
Daniel assumes the tomato has always been beloved. What follows traces the suspicion, the nightshade connection, the fascinating etymology of wolf’s peach, the disputed pewter plate theory, and the slow rehabilitation of the tomato through Mediterranean cooking. The episode closes on pizza, and on the observation that the fruit once feared across parts of Europe became the base of one of the world’s most recognized cuisines.
MomDaniel, what is your favorite thing to put on your pizza?
DanielMom, it's tomato sauce. Obviously. Right.
MomNow, what if I told you that when tomatoes first arrived in Europe, many people were suspicious of them? And in some parts of Europe, that suspicion lasted for generations. They were associated with poisonous nightshades. They were called wolf peaches. Some writers even warned that eating them could make you sick.
DanielTomatoes? Wolf peaches? Are you serious?
MomYes, the very ones. On your pizza.
DanielOkay, where did that actually come from? Or are you just making it up?
MomSo, tomatoes came from the Americas. Their wild ancestors have deep roots in South America. But people had already been cultivating tomatoes in Mexico before Europeans arrived. Spanish colonists brought them to Europe in the 1500s, and when Europeans first saw them, they were immediately suspicious.
DanielHmm, why suspicious?
MomBecause the tomato belongs to the nightshade family. And the nightshade family includes some genuinely poisonous plants. Deadly nightshade. Mandrake. Plants that European botanists already knew were dangerous.
DanielSo the tomato arrived looking like a cousin of something that could kill you.
MomAnd it does contain a compound called tomatine in its leaves and stems. So the suspicion was not completely without reason. But the ripe fruit is safe. European botanists did not know that distinction. Yet.
DanielSo what else made them scared of it?
MomThe tomato also looked suspiciously similar to plants Europeans already feared. Mandrake and deadly nightshade had long been connected with poisons and stories about witchcraft. And botanists gave it an especially strange name. Lycopersicon. Wolf peach.
DanielWhy wolf peach?
MomHere is the strange part. That name was actually much older than the tomato itself. Renaissance botanists were trying to match this strange new fruit to plants described in ancient books. They attached the old name to the tomato. And it stuck.
DanielSo even the name came from people trying to figure out what this strange new plant was.
MomThere is also a famous story that adds to this. Some historians have suggested that Europeans eating from pewter plates, which contained lead, may have been made ill when the tomato's acidity reacted with the metal. The tomato got the blame for what the plate may have caused.
DanielSo the tomato was innocent. And the plate was the problem?
MomThat is the story. And it is a wonderful one. But chemists have questioned whether tomato acidity could realistically leach enough lead to cause illness. What we know for certain is that the tomato already looked suspicious because of its relatives. And influential writers kept repeating that it was unhealthy.
DanielSo while much of Europe was refusing to eat them, was anyone actually trying them?
MomSouthern Europeans, particularly in Spain and southern Italy, began experimenting with the tomato. While other regions remained wary. They cooked with it. They preserved it. They discovered it was actually rather good. One of the earliest surviving European recipes for tomato sauce appeared in Naples in 1692 in a cookbook by Antonio Latini.
MomHe called it a Spanish-style sauce. Not pasta sauce yet, but the tomato was starting to become food rather than a botanical curiosity.
DanielSo generation by generation in Naples, people just kept cooking with it. And the fear quietly fell away.
MomExactly. By the 19th century, tomato-based dishes were already established as inexpensive street food in Naples. The tomato that botanists had feared became the base of an entire cuisine.
DanielSo the wolf's peach that botanists classified alongside poisonous nightshades and that influential writers said was unhealthy became one of the most familiar foods on earth.
MomSometimes a food does not become normal because scientists announce it is safe. It becomes normal because generation after generation of people cook with it and discover the fear was misplaced. So Daniel, what is one thing you are taking with you today?
DanielLet me think hard. Tomatoes arrived in Europe in the 1500s and many people were suspicious of them because they looked like cousins of poisonous plants. There is a famous story about pewter plates and lead poisoning, but chemists have questioned how much of that is actually true.
DanielAnd oh yeah, what we know is that southern Europeans kept cooking with tomatoes anyway, and one of the earliest surviving recipes appeared in Naples in 1692.
MomThe wolf's peach became the world's favorite pizza topping.
DanielI am going to think about that every single time I eat pizza from now on.
