Arnau Pérez de Tudela Guasch is from Valls and runs a communications agency in Altafulla. A few years ago, Gerard Cañellas Prades, from Riera de Gaià, joined the agency. They both always said they had to do something to bring together everything in the world of calçots (where to make them, where to buy them, where to find the sauce...) and one day they had a lightbulb moment. Inspired by the hit app where people noted where to make hearty breakfastsThe CalçotApp has arrived.
