Ice Black tea soda: Put hot water in a teapot and simmer for 3 minutes.
After 3 minutes, pour black tea into the cup.
Add amorphous sugar and mix well.
And I brought you another cup.
I filled two cups of ice in half.
I'm going to mix the two up and down. After some mixing,
pour tonic water and mix it well.
Without tonic water,
you can add Sprite, sparkling water, whatever you like.
