In a pot, bring 2 cups of water to a boil.
While waiting for the water to boil, mix the grass jelly powder, sugar, and salt in a bowl.
Once the water boils, turn off the heat and pour the grass jelly mixture into the pot. Stir the mixture until the powder is completely dissolved
Pour the hot grass jelly mixture into the cups or glasses, leaving some space at the top for the grass jelly to solidify
Let the grass jelly cool to room temperature, then refrigerate for at least 2-3 hours or until it solidifies
Cut the solidified grass jelly into cubes or desired shapes and serve chilled. Enjoy!
