Very easy, 1 packet of gui ling gao (RM20) from Eu Yan Sang contains 5 X 50g of powder

Recipe:

250 ml cold water mixed with 1 pack of 50g gui ling gao powder

Boil 1.7 litre of water with 150g sugar (original recipe specify only 1 litre of water, increased the water since i prefer soft jelly, and previous time i followed their water amount turns out quite hard)

Mix the cold mixture into boiling water, boil for 1 minute of so

Sieve into individual container/bowl

For 50g of powder, i made 7 portion as above (ie RM4 powder to 7 portion!)

In summary, 50g powder + around 1.95 litre water
