Whisk together the soy sauce, ginger, gin, water, sugar and salt in a small bowl. Arrange wings in a single layer in baking dish. Pour the soy sauce mixture over the wings. Allow wings to marinate 30 minutes.
Pour oil into a 2 litre saucepan then heat oil to 190 degrees C. Drain and discard marinade from wings. Cook wings in batches in heated oil until brown and no longer pink on inside; 10 to 15 minutes. Drain cooked wings on paper towels before serving.
