Step 1

In the Instant Pot, combine the water, tea bags, boba pearls, and sugar.

Step 2

Secure the lid on the pot. Close the pressure-release valve. Select MANUAL/PRESSURE COOKER and set the pot at HIGH pressure for 5 minutes. At the end of the cooking time, allow the pot to sit undisturbed for 10 minutes, then quick-release any remaining pressure. (If the pot starts to spew liquid, close the valve and try again in a minute or two.)

Step 3

Remove the tea bags and stir in the evaporated milk.

Step 4

Fill four glasses with ice. Pour the tea over the ice, evenly distributing the boba pearls among the glasses. Serve.
