If Singapore has a dish, this is it. Hainanese chicken rice...which apparently isn't from Hainan at all, but instead came from the Hainanese people who migrated to Singapore.
This dish is simple in that not many ingredients are used, but this puts the emphasis on cooking those few ingredients to perfection.
Remember that the chicken is the star here and it's essential that the chicken be flavourful and cooked just right. Overcooked chicken will be dry and horrible.
