Multi-colour Sago Jelly (recipe taken from Delightful Sweet Treats)
Ingredients
(A) 70 gm sago
(B) 2 tbsp agar agar powder
220 gm caster sugar (I cut down to 180 gm)
½ tsp salt
300 ml thick coconut milk
1000 ml water
(C) a bit of green and red colouring (I used 4 colours)
Method:
Soak sago in water for 10 minutes. Boil a pot of water and put the sago in. Stir to avoid sago from sticking.
Cook sago until transparent. Wash and drain dry. Divide into 2 portions and colour one portion red and one portion green. (Because I used 4 colours, I divide into 4 portions.)
Boil ingredients (B) and sieve. Divide above into 4 portions. Add each colour sago into each portion. Pour first portion into a mould. When slightly harden, pour second portion in. Let it set a little and followed by third portion. Do this until you finish all four portions.
Chill well before unmoulding.
