Step 1: Chill your ingredients
Start by chilling your cranberry juice, pineapple juice, and grenadine in the refrigerator for at least an hour. A cold base will help maintain the temperature of the drink without relying too much on ice (which can dilute it).

Step 2: Mix the juices
In a large pitcher or punch bowl, pour in the 2 cups of cranberry juice and 1 cup of pineapple juice. Stir gently to combine. These two juices are the base of your punch, providing a balance between tart and sweet.

Step 3: Add grenadine for color and depth
Add 1 tablespoon of grenadine to the mixture. Stir gently again. Grenadine will add a rich red tint to the punch and contribute a subtle pomegranate sweetness that enhances the fruity profile.

Step 4: Add ice and garnish
Fill serving glasses or the punch bowl with ice cubes to keep the drink refreshingly cold. Add pineapple slices and halved strawberries as garnish. These not only make the punch look stunning but also add fresh aroma and flavor over time.

Step 5: Serve and enjoy
Pour the punch into glasses and serve immediately. You can also prepare it ahead of time and refrigerate without ice, then add the ice and garnish just before serving.
