01 - Remove grapes from stems, rinse under cold water, and pat completely dry with paper towels to ensure coating adheres properly.
02 - Place dried grapes in a large mixing bowl. Drizzle with fresh lime juice and optional agave syrup or honey. Toss gently until evenly coated.
03 - Sprinkle Tajín seasoning over the grapes, tossing continuously until all grapes are evenly covered with the spicy-sour mixture.
04 - Spread coated grapes in a single layer on a parchment-lined baking sheet, ensuring none are touching for even freezing.
05 - Transfer baking sheet to freezer and freeze for at least 2 hours, or until grapes are completely frozen solid.
06 - Serve frozen directly from the freezer for optimal texture. Store any leftovers in an airtight container for up to 2 weeks.
