01 - Combine pineapple chunks and strawberries in a blender. Process on high speed until completely smooth and no chunks remain.
02 - Pour the blended fruit mixture through a fine-mesh sieve into a large pitcher. Use the back of a spoon or spatula to press down firmly, extracting as much juice as possible. Discard the remaining pulp.
03 - Add freshly squeezed lemon juice and granulated sugar to the strained fruit puree. Stir continuously for 2-3 minutes until sugar is completely dissolved.
04 - Pour cold water into the pitcher and stir thoroughly. Taste the mixture and add additional sugar if desired, stirring until incorporated.
05 - Refrigerate the pineapple pink lemonade for at least 30 minutes, or until completely chilled. For best results, chill 1-2 hours before serving.
06 - Fill serving glasses with ice cubes. Pour chilled lemonade over ice. Decorate each glass with pineapple wedges, fresh lemon slices, and mint sprigs. Serve immediately.
