Melt the slab sugar in half a cup of water.
Add warm water to glutinous rice powder, and mix into a soft dough. Divide into smaller portions,then shape into small round balls. Bring a pot of water to the boil and add in the small pieces of dough. Cook until it floats, then drain from water and let cook in the syrup for 1 minute and take out, draining excess syrup.
Place on plate, and sprinkle crushed peanuts and sugar on top and serve warm.
