Start by peeling the pineapple and slicing it into bite-sized chunks. Set these aside while you mix the batter.

In a large bowl, combine the all-purpose flour, sugar, baking powder, and a pinch of salt. Slowly pour in the sparkling water, whisking until you achieve a smooth and slightly thick batter.

In a deep frying pan, heat about 2 inches of vegetable oil to 350°F (175°C). You can test if it’s hot enough by dropping a small amount of batter into the oil; it should sizzle and rise to the surface.

Dip each pineapple chunk into the batter, ensuring it’s completely coated. Carefully drop it into the hot oil, frying a few at a time. Fry until golden brown and crispy, about 3-4 minutes per batch.

Use a slotted spoon to remove the fritters from the oil, placing them on a paper towel-lined plate to absorb excess oil. Dust with powdered sugar before serving, if desired!
