Take the required quantity of china grass strip (agar agar strands) Here I took 2.5 gms of it.
Rinse the china grass strips twice. Then soak in water for 20 minutes.
In the meanwhile. Heat 250 ml milk. When the milk comes to a boil, add crushed cardamom, saffron and sugar. Mix well. Let milk simmer for a minute. Switch off flame. Cover milk and set aside.
After having soaked china grass strips in water for 20 minutes (step 2), discard its water.
To this soaked china grass strips, add half cup fresh water and let it come to a gentle boil.
Heat on medium flame. Keep stirring so that the strips dissolve uniformly. Patience needed.
In the meanwhile, bring back the flavored milk to flame so that it very well hot when dissolved china grass is mixed into it.
When the strips dissolve into the simmering water, strain this water into the flavored hot milk.
Stir for a minute or two keeping low flame. No need to boil again. Then switch off the flame.
Thereafter strain this agar agar milk into a fancy dish or dessert glasses to set. Garnish with pistachio and almond slivers.
When slightly set, place in refrigerator for 3-4 hours at least.
Serve as a chilled dessert.
