Warm milk and tea bags over medium heat, stirring occasionally. Bring it to a boil, then turn off the heat and let the milk cool while the tea continues to steep. Once cooled slightly, refrigerate it for 1 hour while you prepare the other ingredients. Discard the tea bags.
4 bags black tea, 4 cups whole milk
Brown Sugar Syrup
In a medium saucepan over medium heat, combine brown sugar and water. Stir until sugar dissolves, about 5 minutes, then remove from heat.
2 cups brown sugar, 1 cup water
Brown Sugar Boba
Follow the instructions on your package. For quick-cooking boba: Bring water to a boil in a large pot. Slowly, add the black tapioca pearls.
8 to 10 cups water, 1 cup uncooked black tapioca pearls
Once they float, cover pot and cook over medium heat, 3-5 minutes. Turn off heat, letting them continue to cook for 2 minutes for al dente boba or up to 5 minutes for softer boba.
Strain, then rinse with cold water for 20 seconds to stop the cooking. Transfer to a bowl. Top with brown sugar syrup and cover for 10 minutes. Use within a few hours.

¼ to ½ cup brown sugar boba
Drizzle spoonfuls of brown sugar syrup to decorate the glass for the "tiger" stripes.
