In a high-speed blender, add pineapple chunks, cranberry juice, lemon juice, and water.
Add honey or maple syrup if you prefer a touch of sweetness. Blend until smooth.
Pour the mixture through a fine mesh strainer into a large jug to remove pulp (optional).
Pour the juice into glasses over ice. Garnish with mint leaves or a pineapple wedge for an aesthetic touch.
For a colder drink, refrigerate for 15 minutes before serving.
