My favourite dessert at yum-cha (dim sum) when I was a child was coconut jelly, it has a delicious smooth flavour and texture. The best thing about this jelly is it is so easy to make. Coconut jelly is set with agar agar which is a seaweed that is used in East Asia as a setting agent like gelatin. Agar Agar comes in numerous form eg. Powder, flakes and sticks. You will need different amounts of agar agar according to the variety you are using: 1 tbsp agar agar powder 750ml, 3 tbsp agar agar flakes per 750ml and 3 sticks per 750ml;
