1In a large pot, bring the water to a boil and add the salt. Pour the cornmeal in a steady stream, stirring continuously with a whisk to prevent lumps.
2Reduce the heat to low and cook the polenta for 15–20 minutes, stirring often, until it thickens and pulls away from the sides of the pot.
3Cut the polenta into equal pieces using a piece of string, then let it cool slightly so you can work with it.
4Wet your hands with water. Take each piece of polenta, press a generous amount of cheese (grated or cubed) into the center, and shape into a compact ball the size of a tennis ball.
5Preheat the air fryer to 200°C (400°F) for 3 minutes. Cook the balls for 25 minutes, then add butter and cook for another 5 minutes.
