For the apple fritters

1. Peel the whole apples, slice off each end to create straight edges, then slice horizontally into quarter-inch rounds. Cut out the core of each slice. Rub each slice with lemon to prevent browning, and place them in a bowl. Repeat with remaining apples.
2. Mix together sugar and cinnamon, sprinkle over the apples, and toss to coat. Let stand for 15-20 minutes.

For the batter

1. In a bowl, whisk together flour, milk, egg, baking powder, and salt until smooth. Adjust the batter’s thickness by adding more flour or milk as needed.

To cook

1. Heat oil in a deep fryer to full heat.
2. Using metal tongs, dip apple slices in batter, ensuring they are fully covered, and carefully drop into the hot oil. Add as many slices as the fryer can accommodate without overcrowding.
3. When golden brown, flip fritters to cook the other side.
4. Remove fritters from oil, shaking off excess oil, and place on a plate lined with absorbent kitchen paper to drain.
5. Repeat with remaining fritters.
6. Transfer fritters to a serving plate, dust with icing sugar, and serve immediately.
