In a large, deep mixing bowl, combine glutinous rice flour and water (gradually). Mix until thick and sticky, then form into balls and flatten. Set aside.
Bring a half full of water in a pot to a boil. Drop slowly the dough one by one. Boil until they float. When it floats, it's cooked. Use a skimmer or slotted spoon to scoop and drain the palitaw. Slightly cool them on a plate. Use the same pot and water to cook for the next batch.
Dredge in roasted sesame, sugar, sweetened coconut flakes or combinations of the three. Serve.
