Find me a drink that's mainly made with dark rum on the rocks, a dash of grenadine, and maraschino cherries.

If you're looking for a cocktail that closely matches your preferences—mainly made with dark rum, complemented by a dash of grenadine and garnished with maraschino cherries—while none of the cocktails exactly fit your criteria, the closest match is the "Red Night Dream." This drink combines the bold flavor of white rum, orange juice, and grenadine, garnished with a wedge of pineapple and cherry. While it uses white rum instead of dark rum, you could easily adjust the recipe by substituting dark rum to better fit your tastes.

The "Red Night Dream" has a vibrant and tropical profile, making it visually appealing and refreshing. It's served in a brandy glass, which adds a sophisticated touch to your cocktail experience. The sweetness of the orange juice, combined with the tartness of the grenadine and the rich flavor of dark rum, would likely result in a delightful, balanced drink. Simply follow the original recipe and don't forget to add the maraschino cherries for that perfect finishing touch!
