Using a hand blender (or a blender), blitz the egg and milk with half of the sweetcorn until smooth.
In a mixing bowl place the flour and baking powder. Lightly beat in the sweetcorn puree – you don’t want to overbeat – then fold in the rest of the sweetcorn and sliced spring onions.
Heat a frying pan over a medium heat and add a little olive oil (½ - 1 tsp).
Place dessertspoonfuls of the mixture in the pan fry for 4-5 minutes each side, until lightly golden. Bubbles appear when they are ready to turn.
You may need to do 3-4 batches depending on size of your frying pan.
