It might be hard to go back to regular iced tea ever again.
- 4 ounces chilled brewed black tea
- 3 ounces fresh lime juice
- Mint sprigs (for serving)
Combine vodka, simple syrup, tea, and lime juice in a blender and freeze 3–12 hours (mixture will be partially frozen).
Add 2 cups ice to mixture and blend until thick and smooth. Divide among glasses and garnish with mint sprigs.
