01 - Remove grapes from stems, rinse thoroughly, and dry completely with paper towels. Excess moisture prevents proper seasoning adhesion.
02 - Place dried grapes in a large mixing bowl. Drizzle with fresh lime juice and agave syrup if using. Toss gently to ensure even coverage.
03 - Sprinkle Tajín seasoning over the grapes while tossing continuously. Continue until every grape displays a uniform coating of the spicy-sour blend.
04 - Spread the seasoned grapes in a single layer on a parchment-lined baking sheet. Ensure grapes do not touch for optimal freezing.
05 - Transfer the baking sheet to the freezer. Chill for at least 2 hours or until grapes are completely frozen through.
06 - Serve immediately from the freezer for the best texture and flavor experience. Store leftovers in an airtight container for up to 2 weeks.
