Place the lychees in a food processor and puree until very smooth. Add the brewed black tea, lime juice and lime zest and pulse a few times to incorporate well. Transfer the mixture to a 10 by 10-inch pan. Freeze overnight.
Using the bottom of a fork, scrape the granite into the hollowed out limes. Scrape a small amount of the granite onto the centers of the plates and top with the filled limes (2 halves per plate).
Garnish with the reserved lime zest and serve.
Beverage suggestion: Chinese Tea
