1Boil 4 cups of water in a pot.
Add 3 tea bags to the boiling water and let them steep for 5 minutes.
Remove the tea bags and stir in 1/2 cup of sugar until it is completely dissolved.
Add the juice of 1/2 lemon to the tea mixture and stir well.
Pour the mixture into a shallow dish and place it in the freezer.
After 30 minutes, use a fork to scrape the ice crystals that have formed around the edges and mix them into the center.
Repeat the scraping process every 30 minutes for about 2-3 hours, until the entire mixture is frozen and has a granular texture.
Serve the granita in chilled glasses and enjoy!
