01 - Combine pineapple chunks and halved strawberries in a blender container. Process on high speed until completely smooth and no large pieces remain.
02 - Set a fine-mesh sieve over a large pitcher. Pour the blended fruit puree through the sieve, using the back of a spoon to press firmly and extract maximum juice. Discard the remaining pulp or reserve for another use.
03 - Add the fresh lemon juice and granulated sugar to the strained fruit puree in the pitcher. Stir vigorously with a long spoon until all sugar crystals have completely dissolved.
04 - Pour in the cold water and mix thoroughly. Taste the lemonade and add additional sugar if desired, stirring until incorporated. For sparkling variation, replace 2 cups water with club soda just before serving.
05 - Refrigerate the lemonade for at least 30 minutes, or until thoroughly chilled. This allows flavors to meld and the drink to reach optimal serving temperature.
06 - Fill serving glasses with ice cubes. Pour the chilled pineapple pink lemonade over the ice. Decorate each glass with fresh pineapple wedges, lemon slices, and mint sprigs. Serve immediately.
