01 - Remove grapes from stems. Rinse thoroughly under cold water and pat completely dry with paper towels to ensure the coating adheres properly.
02 - Place dried grapes in a large mixing bowl. Drizzle with fresh lime juice and agave syrup or honey if using. Toss gently to distribute evenly.
03 - Sprinkle Tajín seasoning over the grapes. Toss continuously until each grape is evenly coated with the spicy-sour mixture.
04 - Spread the seasoned grapes in a single layer on a parchment-lined baking sheet or tray, 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.
06 - Serve the grapes immediately from the freezer for the best icy texture and flavor intensity.
