Take 1 and 1/2 cups of water in a mixing bowl. Add rose syrup and pink food color. Mix well.
Now add sugar, whisk it well until sugar completely dissolves, Set aside. In another bowl, cut agar agar into small bits.
Rinse it once then add 1/2 cup and let it to boil. Boil until you see the strands completely dissolved.
Strain to the bowl containing rose water mixture. Mix it well with whisk.
Pour it in the tray/bowl where you want to set the jelly. Leave it undisturbed for 30mins. No need to keep in fridge it will set well in room temperature itself.
Boil milk (reserve a tablespoon of milk) for 5mins until its bubbles up nicely. Simmer and then add sugar. Mix well.
To a tablespoon of milk add custard powder, mix well to form a runny paste without any lumps. Add this to simmering milk.
Keep cooking, slowly it will get thick.
Cook in low flame and keep mixing so that there are no lumps. At one stage the custard will nicely form a thick coating, it will coat the laddle like this, it should be thick as shown below. At this stage, switch off and cool down completely.
First spoon the custard as first layer. I didnt want set jelly as I have tried it here so instead scooped out and added it to the glass on top.Serve chilled!
