Thai people in the northern and northeastern regions eat sticky rice (also known as sweet rice or glutinous rice) in place of long grain rice. It is eaten with your hands by making a little ball and dipping it into other dishes.
While most people used to make it with a steamer, the microwave seems much easier. The grains come out a little stickier, but unless you are eating with your hands, you barely notice.
When you choose your rice, make sure you buy and use sticky rice. Sticky rice is not jasmine rice. If you try to cook jasmine rice this way, it will cook, but it will not taste or feel like sticky rice. Sticky rice has whitish grain as opposed to opaque like jasmine rice.
