Ginger-Pineapple Spritzer

Pour the unsweetened pineapple juice into a large pitcher.

Add the chopped crystallized ginger to the pitcher and stir well to combine the flavors.

Let the mixture steep for 20-30 minutes at room temperature, allowing the ginger to infuse into the juice.

Strain the mixture through a fine-mesh sieve into a clean pitcher, discarding the ginger solids.

Refrigerate the ginger-infused pineapple juice until chilled, about 1-2 hours (or place in the freezer for 30 minutes if time is limited).

Fill serving glasses halfway with ice cubes.

Pour the chilled ginger-pineapple juice into each glass, filling it about three-quarters full.

Top each glass with chilled carbonated water and stir gently to combine without losing carbonation.

Garnish with a skewer of fresh pineapple chunks if desired, and serve immediately.
