TO COOK IN THE AIR-FRYER
Heat the air-fryer to 200C. Prepare the chips up to the end of step one, then toss with the cornflour and 2 tbsp rapeseed oil. Cook for 25-30 mins, shuffling the basket now and then. Prepare the fish as described and, in the final 10 mins of cooking, put a wire rack insert over the chips in the air-fryer and lightly brush over some oil. Arrange the fish on the oiled rack and cook for 10-15 mins, depending on the thickness. (Depending on the size of the air-fryer, you may need to do this in batches.)
