In a saucepan, bring 500ml of water to a boil.
600 ml water
In a separate bowl, dissolve the grass jelly powder in 100ml of cold water.
1 packet
Once the water in the saucepan is boiling, add the sugar and stir until completely dissolved.
50 g sugar
Slowly pour the dissolved grass jelly powder into the boiling water, stirring constantly to prevent lumps from forming.
Let the mixture simmer on low heat for about 15 minutes, stirring occasionally.
Once the liquid has thickened to a jelly-like consistency, remove the saucepan from the heat.
Transfer the mixture to a mold or container, allowing it to cool to room temperature.
Once cooled, refrigerate the grass jelly until it is completely set and firm. This usually takes about 3-4 hours.
Once set, cut the grass jelly into cubes or desired shapes and serve chilled.
