Have 4 clean jars ready. Set aside.
In a large measuring cup, measure out 3 T of cold water.
Sprinkle gelatin over top of the cold water. Set aside and allow to bloom.
Meanwhile, pour ½ can coconut milk and set aside.
Pour the remainder of the coconut milk into a small sauce pan. Add in the sugar.
Heat the coconut milk and sugar over medium heat, just until the liquid is about to boil, about 2 minutes. Stir to dissolve the sugar. Remove from heat.
Whisk the heated coconut milk into the gelatin, making sure that the gelatin has dissolved.
Add in the unheated coconut milk and whisk the mixture gently.
Carefully pour the mixture through a sieve equally into the 4 jars.
Place the jars onto a small tray and put into the refrigerator to chill for at least 4 hours, or overnight.
