Make a batter by sifting flour into a bowl. Make a well in the centre. Whisk milk and eggs together in a small bowl. Add egg mixture to flour and whisk until smooth.
Place the peas in a bowl and mash about half of them. Add peas, feta, mint and onion to the batter. Add sea salt and freshly ground black pepper to taste.
Heat the oil in a non-stick frying pan over medium heat.
Dollop 4 heaped tablespoons of the mixture into the frying pan and flatten slightly with the back of the spoon. Cook for 2-3 minutes on each side until they are golden-brown.
Drain on paper towel. *
Repeat with the remaining batter, adding extra oil if required.
