Step 1: Prepare the Apples

1. Wash and dry the apples thoroughly.
2. Core the apples using a sharp knife or apple corer.
3. Slice the apples into 1/4-inch thick rings.

Step 2: Make the Batter

1. In a mixing bowl, combine the flour, cornstarch, baking powder, salt, cinnamon, and nutmeg.
2. In a separate bowl, whisk together the milk, egg, and vanilla extract.
3. Gradually add the wet ingredients to the dry ingredients, whisking until smooth.

Step 3: Heat the Oil

1. Pour vegetable oil into a deep frying pan or skillet, filling it about 1 inch deep.
2. Heat the oil over medium heat until it reaches 350°F (175°C).

Step 4: Coat and Fry the Apple Rings

1. Dip each apple ring into the batter, ensuring it’s fully coated.
2. Carefully place the coated rings into the hot oil, frying 2-3 at a time to avoid overcrowding.
3. Fry for 2-3 minutes on each side, or until golden brown.
4. Use a slotted spoon to remove the rings and place them on paper towels to drain excess oil.

Step 5: Coat with Sugar

1. While the rings are still warm, sprinkle them with granulated sugar or dip them in a cinnamon-sugar mixture.
2. Serve immediately for the best taste and texture.
