Make the tea: Add the tea bag to the boiling water and let the tea steep for 5 minutes. Remove the tea bag and let the tea cool to room temperature. Then put the tea in the fridge to fully chill. 

Make the strawberry syrup: Heat the strawberries, water and sugar on a pan over medium heat, stirring occasionally. As the strawberries warm up, they will begin to get mushy. Use a fork to fully mash them as much as possible. Continue to stir the syrup, letting it gently simmer for 5-10 minutes. Remove the syrup from the heat and let it cool for a few minutes. 

Strain the syrup: Once slightly cooled, strain the strawberry syrup mixture through a fine mesh sieve. Press the mashed strawberries as much as you can to get all the syrup out of them. You should end up with about a ½ cup of syrup. Set the syrup aside for now. 

Make the boba: Bring a pot of water to a boil on the stove. Once boiling, add the boba to the water. At first, the boba will sink to the bottom, then after about 20 seconds, they will float to the top. Slightly lower the heat and continue to simmer for 5 - 10 minutes. Remove the pot from the heat and strain the boba. Run the boba under cold water for about a minute until they have cooled down. Then, stir them into the strawberry syrup to prevent them from clumping together. 

Put everything together: Stir the chilled tea, milk, and boba in the strawberry syrup together. Add in a handful of ice and serve immediately.
