Ingredients for soup: (agak agak)

2 pieces of pork bones with some meat

a bunch of cranberry beans (peel skin off)

Few pieces of dried scallop

Method:

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.
