I haven't tried this out yet, but I love boba tea, and I'd love to give it a try!
Why do homemade tapioca pearls sometimes turn out chalky in the center or dissolve into mush in the glass? Achieving the ideal chewy texture relies on a controlled heat transition: boiling the dried pearls until they float, reducing the burner to medium for 12 minutes to let the heat penetrate the starch, and then trapping residual heat by covering the pan off the burner for another 12 minutes.
Proper starch hydration separates a professional-quality chew from a dense, unpleasant center. Respecting the resting phases ensures the structural integrity of the tapioca remains intact from the stove to the final wide straw.
