I used a 1.5litre thermal pot (2 pax portion)
Ingredients: (agak agak)
2 pieces of pork bones with some meat
1 corn (break into 2)
Few pieces of dried scallop
3 red dates
Blanched pork bones with hot water.
Put them in inner pot, add in other ingredients.
Pour in hot water till 80% full and bring the whole pot to boil for about 10 mins.
Then cover and put in the outer pot and close lid.
I let it sit in the pot till after work. Approximately 12 hours.
When came home from work, the soup is still warm.
I heat it up on stove and add noodles, mushroom, fishball and beancurd skin.
