Making Fried Pineapple Rings is simple, and these steps will guide you through the process:

1. Prepare the Pineapple: Start by slicing the pineapple into 1/2-inch thick rings. Remove the core from each ring with a small cookie cutter or knife.
2. Make the Batter: In a mixing bowl, combine the all-purpose flour, cornstarch, granulated sugar, baking powder, and salt. Mix thoroughly.
3. Add Water: Gradually stir in the cold water and vanilla extract (if using) until you achieve a smooth batter. The consistency should be thick enough to coat the pineapple rings.
4. Heat Oil: In a deep skillet or frying pan, heat about 1 inch of vegetable oil over medium heat until it reaches 350°F (175°C). You can test if the oil is ready by dropping a small amount of batter in; if it sizzles and rises to the top, it’s ready for frying.
5. Coat the Pineapple: Dip each pineapple ring into the batter, ensuring both sides are fully coated.
6. Fry the Rings: Carefully place the battered rings into the hot oil, frying them in batches to avoid overcrowding. Fry for about 2-3 minutes per side or until golden brown.
7. Drain Excess Oil: Using tongs, remove the fried pineapple rings from the oil and place them on a paper towel-lined plate to soak up any excess oil.
8. Dust with Cinnamon: While they are still warm, sprinkle the fried rings with ground cinnamon for added flavor.

These simple steps will yield perfect Fried Pineapple Rings that are sure to impress!
