A Toast Story

How did toast become the latest artisanal food craze? Ask a trivial question, get a profound, heartbreaking answer.

The menu also features a go-for-broke option called “Build Your Own Damn House,” which consists of a coffee, a coconut, and a piece of cinnamon toast. Hanging in the door is a manifesto that covers a green chalkboard. “We are local people with useful skills in tangible situations,” it says, among other things. “Drink a cup of Trouble. Eat a coconut. And learn to build your own damn house. We will help. We are building a network.”

At first, Carrelli explained Trouble as a kind of sociological experiment in engineering spontaneous communication between strangers. She even conducted field research, she says, before opening the shop. “I did a study in New York and San Francisco, standing on the street holding a sandwich, saying hello to people. No one would talk to me. But if I stayed at that same street corner and I was holding a coconut? People would engage,” she said. “I wrote down exactly how many people talked to me.”

If the spread of toast is a social contagion, then Carrelli was its perfect vector. Most of us dedicate the bulk of our attention to a handful of relationships: with a significant other, children, parents, a few close friends. Social scientists call these “strong ties.” But Carrelli can’t rely on such a small set of intimates. Strong ties have a history of failing her, of buckling under the weight of her illness. So she has adapted by forming as many relationships—as many weak ties—as she possibly can. And webs of weak ties are what allow ideas to spread.
