01 - Remove grapes from stems. Rinse thoroughly under cool water and dry completely with paper towels. Moisture prevents the seasoning from adhering properly.
02 - Place the dried grapes in a large mixing bowl. Drizzle with fresh lime juice and add agave syrup or honey if using. Toss gently but thoroughly to ensure every grape is lightly coated.
03 - Sprinkle the Tajín seasoning evenly over the grapes. Toss continuously until all grapes are uniformly coated with the spicy-sour blend. Add more Tajín if desired.
04 - Line a baking sheet or tray with parchment paper. Spread the seasoned grapes in a single layer, ensuring they don't touch each other for optimal freezing.
05 - Transfer the baking sheet to the freezer. Freeze for at least 2 hours, or until the grapes are completely frozen solid. For best results, freeze overnight.
06 - Serve the frozen grapes immediately, straight from the freezer, while they're firm and icy. Store leftovers in an airtight container in the freezer for up to 2 weeks.
