Taro and Tapioca Dessert

This is one of my favorite desserts when we go to restaurants. But the restaurants have a tendency to make it too sweet. Now that I've found the recipe for it, may be I'll make it myself so it won't be too sweet. Haha.

Ingredients:
0.70 lb taro diced
1/2 cup tapioca pearls
1 1/2 cup coconut milk, to taste
rock sugar, to tast
4 1/4 cup water

1. Soak tapioca pearls over 3 hours. Add to the boiling water on medium heat. Stir them frequently and make sure that they don’t stick together. After cooking for 20 minutes, remove the pot from heat, cover and let sit for another 30 minutes. The tapioca pearls should be translucent, without any white dots in the middle. They are done. If they are not ready, turn on the heat again and cook for a few minutes more. And then let sit for a while again.
2. Drain tapioca pearls and rinse under cold water. All tapioca pearls should be cool to the touch.
3. Bring water and coconut to the boil, add diced taro. When the taro cubes are cooked half through, add rock sugar until melted, to your taste. Lastly, add cooked tapioca pearls. Done.

Serve hot or cold.
