The Cold Slurry: In a small, unheated saucepan, whisk together the fruit juice, honey, and cornstarch.
Note: Ensure the cornstarch is completely dissolved in the cold juice before turning on the heat to prevent lumps.
The Thicken & Stir: Turn the stove to medium heat. Stir the mixture continuously using a whisk or spatula.
The Glossy Finish: As the mixture begins to simmer and thicken, lower the heat. Continue stirring for a total of 5–7 minutes until the liquid becomes translucent, glossy, and very thick.
The Pour: Immediately transfer the hot mixture into a small glass container or silicone molds.
The Set: Allow it to cool at room temperature for 30 minutes, then transfer to the refrigerator for 1 hour to achieve maximum "jiggle."
The Finish: Gently demold the jelly. Slice into even cubes and roll each piece in desiccated coconut until fully coated.
Serve: Enjoy immediately as a refreshing, chilled snack!
