In a mixing bowl, combine the cooled pap, flour, baking powder, salt, and pepper.
Add the egg and mix well until combined.
Stir in the sweetcorn and cheese if using.
Gradually add milk — the mixture should be thick but scoopable.
Heat a thin layer of oil in a pan over medium heat.
Drop spoonfuls of batter into the pan and flatten slightly.
Fry for 2–3 minutes on each side until golden brown and crisp.
Drain on paper towels and serve warm.
