First, use a knife to crush the cane sugar to allow it to easily melt.
Next, boil 3 cups of water, then add ginger and cane sugar on low heat until the cane sugar is melted.
Then, add rice balls and switch to high heat. Add one more cup of water after it boils. Later, turn on medium heat after boiling. Once the rice balls float, the dessert is cooked and ready.
