01 - Remove grapes from stems, rinse thoroughly, 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 until all grapes are lightly coated.
03 - Sprinkle Tajín seasoning evenly over the grapes while tossing continuously. Ensure every grape receives a dusting of the spicy-sour mixture.
04 - Spread the coated grapes in a single layer on a parchment-lined baking sheet or tray, preventing them from touching for optimal freezing.
05 - Transfer the baking sheet to the freezer and chill for at least 2 hours, or until grapes are frozen completely solid.
06 - Serve the frozen grapes immediately from the freezer for the best texture. Store leftovers in an airtight container in the freezer for up to 2 weeks.
