Ginger steamed milk pudding

I particularly liked a hot ginger steamed milk pudding found in a restaurant called Macau. Searches over the internet end up directing me to western puddings. But I found it at last!

Ingredients
Fresh milk - 1 litre; Ginger - 1 piece; White sugar 5 tbsp

Steps
1) Peel and wash ginger, grate to make 8-10 tbsp ginger juice
2) Filtrate the juice finely, divide into 4 bowl equally
3) Add in sugar, mix with ginger juice
4) Boil fresh milk, keep stirring until fully boiled, turn off the fire
5) Keep slowly stirring until milk becomes a little cooler
6) Pour milk into each bowl quickly
7) Serve few minutes later when milk become solidified


Remarks
Grate the ginger only before use, or milk cannot be form solidified
When milk is boiled, stir about 20 times slowly, it's right time to lower the temperature
Do not pause when pouring the milk into the bowls
Serve in hot temperature is better, or chilled for better feeling in Summer
