Prepare the Tapioca Pearls: Bring 4 cups of water to a rolling boil in a medium saucepan. Add the dried tapioca pearls.

Cook the Boba: Stir immediately so the pearls don't stick. Cook according to package directions (usually 15-20 minutes until soft and chewy in the center). Drain the pearls and rinse briefly under cold water.

Make the Syrup: While the boba cooks, combine 1/4 cup brown sugar and 1/4 cup water in a small saucepan. Heat over medium heat, stirring until the sugar is completely dissolved. Let it simmer for 2 minutes until slightly thickened. Remove from heat.

Soak the Boba: Add the cooked and drained tapioca pearls directly into the brown sugar syrup. Let them steep for at least 10 minutes to absorb the sweetness and achieve a glossy texture. Set aside.

Assemble the Tea: In a cocktail shaker or large jar, combine the cold brewed black tea, milk, and your chosen sweetener (start with 2 tablespoons of the reserved brown sugar syrup or condensed milk).

Serve: Divide the sweetened boba pearls evenly between two tall glasses. Fill the glasses 2/3 full with ice. Pour the milk tea mixture over the ice and boba. Stir well before serving with a wide straw.
