For the patatas bravas
3 tbsp olive oil
600g/1lb 5oz potatoes, such as Maris Piper, Desiree, King Edward, peeled and cut into 2.5cm/1in cubes
salt and freshly ground black pepper
2 x 400g/14oz cans chopped tomatoes
3 red chillies, seeds removed, finely chopped
For the crispy John Dory
6 x John Dory fillets
cornflour for dredging, seasoned with celery salt,
white pepper and smoked paprika
vegetable oil, for deep frying
chopped fresh parsley
Preheat the oven to 225C/450F/Gas 7.
Heat the olive oil in a large roasting tin until very hot. Place the potatoes into the tin and shake them in the oil until covered. Season well with salt and freshly ground black pepper. Place into the oven for about 10 minutes, or until they begin to turn golden-brown.
Add the tomatoes, chillies and garlic and stir until well combined. Cook for another 25-35 minutes, or until the potatoes are tender to the point of a knife.
For the fish, dredge the fillets in the seasoned flour. Fill a deep-fat fryer or a large, deep, heavy-bottomed pan two-thirds full with vegetable oil. Heat the oil to 180C/350F, or until a breadcrumb sizzles. (CAUTION: Hot oil can be dangerous. Don't leave unattended) Fry the fish fillets for two minutes, or until crisp and golden-brown. Remove from the pan with a slotted spoon and set aside to drain on kitchen paper.
Divide the potatoes among six individual serving plates, sprinkle with the chopped parsley and serve with a piece of fish on top of each.
