First of all, sticky rice is actually a type of rice - it's
not a method of cooking. Sticky rice is sometimes called "sweet"
rice or "glutinous" rice.
Unlike the rice we usually
eat, which is cooked in water, sticky rice has to be steamed. So
you'll need some sort of large steamer in order to cook it.
Take 2 cups sticky rice and put in a mixing bowl. Fill with
water and rub the rice vigorously with your hands. The water will
turn milky. Drain off the milky water, replace with fresh water,
and keep repeating the process until the water runs clear.
Soak the rice in clean water overnight.
When you're ready to cook the rice, drain and place in the steamer. (If the
holes in the steamer are too large and the rice might fall through,
line it with cheesecloth first.) Fill the pan with water, making
sure it doesn't touch the steamer. Steam for about 30 minutes
and check it. It might need another 10 minutes or so.
