In a soup pot... combine water, sugar, vanilla extract (or split vanilla Bean), cinnamon stick and Tapioca pearls. Bring it to a boil over medium heat.
When it begins to boil, lower the heat to the lowest temperature.
Cook for 20 minutes, while stirring (if you don't stir, it can burn or get stuck to the bottom). The Tapioca will thicken.
(If you choose to work with cornstarch instead of Tapioca... Bring water/sugar/spices to a boil,. Combine 2 TBL corn starch with ⅓ cup cold water... stir into the boiling sugar water. Let cook 20 minutes.)
Add fruit to the simmering liquid.
Raise the heat, and bring back to a boil.
Simmer for another 5 to 10 minutes (longer if your fruit was frozen).
Add lemon juice.
Sweeten if needed.
Let the soup cool, then store in the refrigerator until cold.
