For the best Tropical Sunrise Punch, use freshly squeezed orange juice to enhance the bright, tropical flavors. To get the perfect sunrise effect, slowly pour the grenadine over the back of a spoon so it sinks to the bottom. You can adjust the sweetness by adding more or less grenadine, and if you prefer a stronger drink, increase the coconut rum. Garnishing with fresh pineapple, orange slices, and cherries adds a fun, tropical vibe that completes the presentation!
