In 2009, Mexican architect Raul Cardenas Osuna enlisted a team of scientists, programmers and artists and to work for his organisation. At Torolab, he wanted them to tackle the biggest problem in the country: violent crime. After months of research, his complex team came up with a simple plan: Start a cookbook.

In the town of Camino Verde in Tijuana, Torolab's cookbook reconnected a traumatised community. They dramatically reduced crime rates. It's working so well in Tijuana that they're now trying it across the border in California.
