While that's going on, set a fine-mesh sieve or infuser over a heatproof glass measuring cup and measure 3 tablespoons of tea mix into the sieve.
When the water is boiling pour about 1 cup over the tea mix and allow it to steep for 10-15 minutes
Once the tea has steeped, remove the sieve and discard the remaining tea leaves. You'll be left with a tea concentrate that we'll further dilute with ice and cool down to make it iced in the process.
Add enough ice so that the water level comes up to 1 1/2 cups.
Stir the tea to melt the ice for about 30 seconds. After this is done your tea should be quite cool
Now measure out about 3-4 tablespoons of sweetened condensed milk and add it to the tea. You'll notice it turns that bright, yet creamy shade of orange!
Now fill a glass with ice and pour your delicious tea over top
Pop in a stainless steel straw and sip away!
Notes
I say 1-2 servings depending on the size of the glass you use to serve it in but if it were me, I'd make this much for just myself :)
