# Steps:
01 - Remove grapes from stems, wash thoroughly in a colander, and pat dry completely with a clean kitchen towel to prevent ice crystals from forming.
02 - Spread the dried grapes in a single layer on a baking sheet lined with parchment paper, ensuring they don't touch each other for even freezing.
03 - If using, lightly drizzle the grapes with fresh lemon juice for a tangy brightness that complements the natural sweetness.
04 - Place the baking sheet in the freezer for at least 2 hours, or until the grapes are completely frozen through and firm to the touch.
05 - Transfer frozen grapes to a serving bowl, garnish with chopped mint if desired, and serve immediately while they remain crisp and refreshing.
