I have tried to make boba, or bubble tea, for close to a year with failure. The issue is that most boba teas contain syrup you can only buy in bulk. The best place to find tapioca pearls in my area is Whole Foods and it is a bit pricey but it is worth it and a little lasts a long way!
To make one serving you will need: 1/2 cup of sugar, 1/3 cup of tapioca pearls, 1 cup of black tea, a cup of ice cubes, two tablespoons of milk (I add agave nectar).
In a small saucepan, bring 2 cups water to a boil. Stir in 1 teaspoon sugar until it dissolves. Toss in the pearl tapioca. Cook for about 20 minutes. Rinse, drain, and refrigerate until chilled.
Have fun with your own unique creations! Enjoy.
