Begin by chopping one fresh pineapple into chunks and place it in a large pot along with 4 cups of water. Bring the mixture to a boil over medium-high heat, then reduce to a gentle simmer for 20-25 minutes.

After simmering, remove the pot from heat and allow the mixture to cool slightly for about 10 minutes. Using a fine-mesh strainer, carefully strain the liquid into a large bowl or pitcher.

In a separate saucepan, combine 4 cups of water and granulated sugar over medium heat. Stir constantly until the sugar completely dissolves, about 5-7 minutes.

In a large pitcher, mix the cooled pineapple-infused water, homemade simple syrup, and freshly squeezed lemon juice. Gradually add cranberry juice until you achieve the desired color.

Give the Pineapple Pink Lemonade a taste and adjust the flavors as necessary. If it's too tart, add more simple syrup or cranberry juice.

Cover the pitcher and refrigerate the combined mixture for at least 2 hours.

When ready to serve, fill glasses with ice cubes and pour the chilled Pineapple Pink Lemonade over the ice. Garnish with lemon slices, pineapple wedges, and sprigs of fresh mint.
