Adam Liaw is in Fujian – a place with a long history of migration where the movement of people left an enduring mark that manifested in its food and culture. Fujian cuisine is known for its huge variety of seafood and wild foods from the mountains. Cooks here have become known for their deft touch with seasonings, vinegar, wines and soy sauces and Adam visits Gulong Soy Sauce Factory, the largest dry yard in Asia that uses the traditional brewing method to turn 55,000 pots of soybeans into soy sauce. It's here that Adam learns about the two-year fermentation process and tastes firsthand the deliciously thick and salty sauce before using it in a local Fujian dish.
