This is a refreshing take on one of summer’s classics. Delicious ripe peaches are blended with black tea and sugar, plus a little lemon juice to enhance the peachy taste. It’s a time-tested chef... trick: lemon juice boosts fruit flavors, similar the way salt boosts savory flavors. You’ll hardly taste the lemon, but you will really taste the peach.
Steep the tea bag with hot water for 3 minutes. Discard the tea bag.
With a food processor or blender, puree the hot tea with the diced peaches until smooth. Stir in the lemon juice and sugar until the sugar is dissolved, then mix in the cold water. Taste for sweetness. Pour into a 9- by 9-inch baking pan. Cover and put into the freezer.
After 1 hour, using a fork, scrape the frozen top layer and break any chunks into pieces. Return to the freezer. Continue to scrape every 15 to 20 minutes until the granita has a fluffy, snowy consistency, about 2 hours. Eat immediately or keep for 3 days in the freezer, scraping every so often.
If you typically drink loose-leaf tea, just make a pot of your favorite black tea and measure out ¾ cup through a strainer.
