my mum will buy the chk drumsticks from wet market, asked the uncle to sepeate the bones n meat. the bones i will cook with wolfberries and red dates for few hours, and pour into the ice cubes, cover the lid and send to the freezer. next day pop them all into freezer bag and put back into the freezer. each time will use 2-3 cubes. usually will wait for the porridge (or other foods) to boil then i will throw in the cubes.
ikan bilis, same thing, use the ikan bilis to boil.. =)
