1. Boil water: Bring 6 cups of water to a vigorous, rolling boil in a medium saucepan. The water needs to be actively boiling before you add the pearls.
2. Add tapioca pearls: Pour the tapioca pearls into the boiling water while stirring gently. Keep stirring for the first 1-2 minutes to prevent sticking.
3. Cook the pearls: Once the pearls float to the surface, reduce heat to medium and continue cooking. For quick-cook pearls, this takes about 5 minutes; for traditional pearls, 15-25 minutes. The pearls are done when they’re completely translucent with no white center remaining.
4. Rest the pearls: Turn off heat, cover the pot, and let the pearls rest in the hot water for another 15-20 minutes. This step is crucial for achieving the right chewy texture.
5. Drain and rinse: Drain the pearls through a strainer and rinse briefly with cool water to stop the cooking process.

Make the Brown Sugar Syrup:

6. Combine sugar and water: While the pearls cook, combine ½ cup brown sugar and ½ cup water in a small saucepan.
7. Heat until dissolved: Cook over medium heat, stirring constantly, until the sugar completely dissolves. Simmer for 2-3 minutes until slightly thickened. Remove from heat.
8. Coat the pearls: Transfer the drained tapioca pearls to a bowl and pour half of the brown sugar syrup over them. Stir gently to coat. Let them soak while you prepare the tea.

Brew the Tea:

9. Boil water: Bring 2 cups of fresh water to a boil.
10. Steep the tea: Add the tea leaves or bags and steep for 3-5 minutes for a strong brew. You want it stronger than you’d normally drink since it will be diluted with milk and ice.
11. Strain and cool: Strain out the tea leaves (or remove bags) and let the tea cool to room temperature, then refrigerate until cold. For faster cooling, steep the tea stronger with 1 cup of water, then add 1 cup of cold water.

Assemble the Bubble Tea:

12. Add boba to glasses: Spoon 3-4 tablespoons of the syrup-coated tapioca pearls into each serving glass.
13. Add remaining syrup: Drizzle 1-2 tablespoons of the remaining brown sugar syrup into each glass (this creates beautiful tiger stripes if you drizzle it down the inside walls).
14. Add ice: Fill the glasses about two-thirds full with ice cubes.
15. Combine tea and milk: In a shaker or pitcher, combine the cooled tea with milk. Add additional brown sugar syrup to taste if desired. Shake or stir vigorously.
16. Pour and serve: Pour the milk tea over the ice and boba. Insert a wide boba straw and serve immediately.
