Notes：
The egg white should be beaten well. Otherwise, your pudding will have some lumps. Yet, no need to beat too hard or too long because you don’t want too many bubbles.
Don't heat the coconut milk mixture too hot. Otherwise, the egg white will be cooked instantly and turn into egg white drops.
If you want smoothest pudding, remember to sift the coconut milk mixture. Or you might want to skip this step if you like.
After sprinkling the gelatine powder, make sure you mix it very well until it’s completely dissolved.
