Prepare the starch mixture: In a mixing bowl, combine the cornstarch, water, and salt (if using). Stir until the mixture forms a thick, smooth paste.
Shape the chunks: Spread the mixture evenly onto a lined baking sheet. Allow it to dry slightly until it’s firm enough to cut into cubes.
Cut into chunks: Once the mixture is firm, use a sharp knife to cut it into bite-sized cubes. Make sure they’re evenly sized for consistent cooking.
Preheat the air fryer: Set your air fryer to 375°F (190°C) and let it preheat for about 3 minutes.
Arrange the chunks: Place the starch chunks in a single layer in the fryer basket. You may need to cook them in batches to avoid overcrowding.
Cook: Air fry for 10-12 minutes, shaking the basket halfway through, until the chunks are puffed up and lightly golden.
Cool and serve: Let the chunks cool slightly before serving. Pair them with your favorite dips or enjoy them as is!
