Bring 5 cups of water to boil in a small pot. Add tapioca pearls to boiling water, and bring down to medium heat. Cook for 15 minutes, stirring frequently to ensure that pearls don't stick together. Once the tapioca are cooked through (test one to ensure that it's soft all the way through), then turn off the heat and let sit in the water for about 10 minutes.

Drain, rinse with cold water, then transfer to a clean jar and add 1/4 cup maple syrup over the pearls. Add a water just to cover the pearls (maybe another 1/4 cup, depending on how big your container is).

Store, covered in fridge for up to 2 days. When chilled, the boba gets hard again. To soften, just reheat in a small pot of boiling water in some of the syrup + water (to cover).

In a small blender, combine soy milk, green tea powder, maple syrup, and ice cubes and blend completely.

Scoop about 1/4 cup of the boba (or however much you want) into a jar/milkshake glass. Pour milk tea over boba and serve with an extra large straw (you can find them at Asian/Chinese markets). Enjoy!
