If u ever visit the island of Hainan today, there's no such thing as hainan chicken rice.
True. On Hainan Island, it's only called Chicken Rice.
Haahahahaha
The spore hainan chicken rice was, over the years, evolved & metamorphed, into a staple food for Sporeans by the early hainan immigrants.
The Hainanese chicken rice as we know was reinvented in sinkapore during the 50s. It's like how the Hamburger (originally a sandwich from Hamburg, Germany) is popularised in America.
On Hainan Island, the chicken is just boiled and rice cooked in chicken stock. No sesame oil, soy sauce etc added to the chicken so it's dry. But because the chickens there are raised in the 'kampung', the meat is less flabby and tastes better.
