John Rocha is a Chinese-Portuguese Eurasian. After years of corporate life in strategic marketing and brand management, John left his own consultancy business and started his new pursuits in 2013. Raised in a family with both Chinese and Western roots, John has learnt how to appreciate different cultures, customs and values since he was a young kid. At a very young age, John began to show a keen interest in culinary art and over the years he has inherited a lot of Macanese heritage cooking recipes and techniques from his beloved Avo (‘Grandma’ in Portuguese) and mom. Realising that fewer and fewer people would know of these recipes as the older generations are gone, he sets out a mission to preserve as many as he can.
In December 2016, John started his own blog Eurasian Food Journey on Facebook and Instagram to introduce and share recipes on Macanese and Portuguese cooking. In January 2017, he started hosting cooking classes in Hong Kong on Macanese and Portuguese cooking, which have been well received by people who love cooking. John has conducted over 200 classes in one year. He is currently a cooking instructor at Towngas Cooking Centre, Bma Home & Kitchen and The Cooking Alley. John also appeared in local media to talk about western cooking and did a special feature in Portugal on food and dining reported on Apple Daily.
