To make the fritters, put the sweetcorn and spring onions in a bowl. Beat the eggs with the milk. Pour this mixture over the sweetcorn and mix well. Season with salt and pepper. Sieve the flour with the cayenne pepper and then stir into the sweetcorn mixture.
Add the oil to a large frying pan – you need to shallow fry these, so make sure the base of the pan is well covered. Heat the oil, then test by adding a tiny bit of the batter – it should immediately start bubbling around the edges when it hits the oil.
Using a small ladle or measuring cup, drop batter onto the oil – you need around 2 tbsp of mixture per fritter.
You should be able to fry 4–5 at any one time. Fry for a couple of minutes on one side until light brown then turn over and cook for a further minute.
Turn out onto kitchen paper to remove any excess oil and keep warm in a low oven. Continue until you have used all the batter.
