Pour the gelatin powder into the glass container. (If you are using a gelatin mold, make the jelly in a glass or heat safe bowl/pot)
Add one cup cold lychee syrup juice. Just strain the lychees from the can and add one cup of the leftover syrup juice.
Bloom the gelatin powder for ten minutes. Whisk the gelatin with the lychee juice very well and let it sit on the counter until the gelatin looks expanded in the liquid.
Heat the one cup coconut juice in the microwave or in a pot until very hot, but not boiling. Add it to the bloomed gelatin mixture.
Wish for five minutes, ensuring the gelatin is completely dissolved. Let cool at room temperature for 15–20 minutes, then transfer to the refrigerator. Chill for at least 2 hours until fully firm.
Cut into small cubes or desired shapes.
