Ingredients:
- 12 cups chilled lemon-lime soda
- 4 cups chilled sparkling water
- 2 tbsp fresh lime juice
- 2 cups grenadine syrup
- 1 cup maraschino cherry juice
- 25 maraschino cherries
- 2 cups fresh lime slices
Instructions:
- Refrigerate all liquid ingredients for at least 4 hours to ensure they are thoroughly chilled.
- Pour the chilled lemon-lime soda and sparkling water into a large punch bowl and stir in the fresh lime juice.
- Slowly pour the grenadine and cherry juice around the inner edges of the bowl, allowing the syrup to sink, then give it one very slow, gentle stir to create a pink swirl.
- Gently add the maraschino cherries and lime slices. Add ice just before serving.
