Notes

  1. There is no substitute for tapioca starch as the main objective of it is to create chewy boba-like water chestnuts. 
  2. Do not overcook water chestnuts as they will turn mushy.  
  3. You may create your simple syrup by combining equal parts of water and white sugar. Simmered down for 5 minutes. 
  4. You may add ice cubes if you like.
