For the best Cranberry Cinnamon Margarita, use freshly squeezed lime juice for a bright, tangy flavor. The cinnamon syrup adds a warm, spicy kick, but you can adjust the amount to your taste. For an extra festive touch, garnish with a cinnamon stick and fresh cranberries, which not only look great but also add a burst of color. Be sure to rim the glass with a cinnamon-sugar mix to enhance the holiday vibe. Serve it chilled over ice for the perfect balance of tart, sweet, and spiced flavors!
