Ixta Belfrage spent her youth dipping her fingers into mixing bowls in places as far-flung as Italy, Mexico and Brazil and so became an expert without a title. She began her culinary career proper at Ottolenghi's NOPI restaurant, before moving to the Test Kitchen, where she has worked for Yotam Ottolenghi for four years, contributing to his columns in The Guardian and The New York Times. She lives in London, where she makes regular guest chef appearances in some of the city's top restaurants. Flavour is her first book.
