Method
Sift 50g flour into a bowl and make a well in the centre. Add the egg and gradually blend in the milk to form a smooth batter. Season with the onion salt.
Cut the chicken into 3-4cm pieces and put in a bowl. Sift the remaining flour and some seasoning on top, and mix well until the chicken is dusted all over. Heat the oil in a deep fat fryer or a large saucepan to 180°C (365°F).
Pour the batter over the floured chicken and mix gently so that all the pieces are covered. Using tongs, lower 6 or 7 pieces of chicken into the hot oil and cook, turning occasionally, for about 7 mins until golden all over and cooked through. Drain on kitchen paper and keep warm whilst cooking the other pieces. Serve as soon as possible after frying accompanied with chips and salad if liked.
