Heat a tablespoon of olive oil in a large frying pan over a medium to high heat. Use a ¼ cup measuring cup to scoop up the batter and place the fritter mixture into your pan.
Use a spoon to gently spread the mixture into a circle between ½ – 1cm thick. You should be able to fit approximately six fritters (or even more depending on the size of your pan) into your frying pan.
Cook the fritters for approximately 2-3 minutes on each side, until they are crisp and golden brown. Transfer the cooked fritters to a plate. Repeat until all the mixture has been used.
