In a food processor, blend the macapuno and its syrup until you get the texture you like, either chunky or smooth. As an alternative, you can chop it finely with a knife.
In a saucepan, combine macapuno, ¼ to ½ cup of sugar, and a pinch of salt.
Cook over medium-low heat, stirring constantly, until it thickens into a paste, which should take 20-30 minutes.PRO TIP: To prevent the sugar from crystallizing, dissolve it slowly over medium-low heat while stirring constantly. Crystallization happens when sugar forms grainy crystals instead of fully dissolving, resulting in a gritty texture. In a bowl, dissolve ½ cup of tapioca starch in ½ cup of water to create a slurry. Pour the slurry into the saucepan and continue mixing until it becomes gelatinous. Cook for another 10-15 minutes, stirring constantly, until the mixture is very thick and holds its shape.
You can add a few drops of pandan extract or ½ teaspoon of vanilla extract as optional flavoring.
Allow the mixture to cool until it's easy to handle, typically a few hours to overnight. Once cooled, oil your hands lightly and shape the mixture into balls.
Roll each piece in granulated sugar until fully coated. As an option, you can individually wrap each one in cellophane.
Store the Macapuno Balls in an airtight container at room temperature for a few days or refrigerate to keep them longer.
