Place the peeled peanuts, drained glutinous rice, and 30-50g of yellow rock sugar into a high-powered blender. Add the 600ml of fresh water.
Secure the lid tightly. If your blender has a "soup," "porridge," or "hot drink" function, select it and let the machine run its full cycle. This will both blend the ingredients into a fine paste and cook the soup.
If your blender does not have a heating function, blend the ingredients on high until completely smooth (about 2-3 minutes).
Then, pour the mixture into a medium saucepan.
Cook over medium-low heat, stirring constantly with a whisk to prevent sticking, for 10-15 minutes until hot, thickened, and the raw rice flavor has cooked out.
