Fill a pot with water and bring to boil. Add boba and gently stir to break up any pieces stuck together.
Unless otherwise instructed by the product package, boil for 30 minutes. Turn off the heat, cover the pot, and let it sit for 20 minutes to finish cooking the core of the boba. Then rinse with water and drain.
In a saucepan, combine 1 cup water and 1/4 cup muscovado sugar. Stir frequently with medium heat for 5 min or until the sugar is fully dissolved.
Add the boba to the syrup mixture. Maintain a low simmer for 10-20 min, stir frequently until the syrup becomes slightly thick. Test the consistency by taking a spoonful of syrup and turning your spoon sideways to let it fall back into the pot. If you tilt the spoon and it falls off slowly, it is ready. If it stays in place, it is too thick so add a little water. If it runs quickly, keep boiling until it becomes a little thicker.
Remove boba/syrup mixture from heat.
