Petra Barran  Petra Barran is a British entrepreneur and the Founder of the London street food collective KERB. In 2005 Barran began her street food career selling chocolate out of an old ice cream van. She has since transformed London's street food scene. As of 2019, KERB has five sites across London, which serve more than 10,000 dishes a week. Barran grew up in Suffolk. She has also lived in Africa and Italy, and became interested in food during her childhood. Barran had a recipe book from Sainsbury's, from which she cooked every item. She was first introduced to street food at the age of ten in Mexico. Her first job was in a local tearoom. Barran studied American Studies at the University of Manchester and earned a bachelor's degree in 1999. After graduating, Barran became interested in chocolate, and trained alongside the chocolatier Pierre Marcolini. From 2005 Barran sold chocolates out of an old ice cream van (named Jimmy) that she used to take to markets and events around the United Kingdom. She toured the United Kingdom, exchanging chocolate pudding for a bed for the night. "Choc Star" became an "acclaimed mobile chocolatier", selling hot chocolate, brownie fudge sundaes and Rocky Road."" At a small festival that Choc Star was due to appear at, despite Barran having pitched and paid the fees, the festival folded days before it opened. When Barran learned that she could not be reimbursed, she became determined to not let this happen to anyone else, and came up with the idea of building a street food collective. In 2005 Barran joined up with two other street food companies and form "Eat Street" in 2009, which became a collective of 32 traders that opened in locations around London. In 2010, whilst on holiday in New York City, Barran decided to study for a master's degree in Urban Studies. She wanted to make cities more interesting through food. She retired her van Jimmy in 2011. That year Barran was selected as one of The Independent "Ten People Who Changed The World". She completed her master's degree at University College London in 2013. She was part of the University College London Urban Laboratory, which is part of The Bartlett and the Department of Geography. Barran launched KERB in 2012. She was determined to make the street food movement accessible for everyone. KERB is a community of street food providers whose customers include permanent London markets and corporate event organisers.
