1 large fennel bulb, trimmed and chopped
2 banana shallots, chopped
1 carrot, peeled and chopped
1 celery stalk, trimmed and chopped
1 tbsp tomato purée
250g/9oz plum tomatoes, chopped
1 star anise
pinch saffron strands
½ tsp cayenne pepper
300ml/10½fl oz dry white wine
2 tbsp pastis
600ml/20fl oz fish stock
600ml/20fl oz chicken stock
400g/14oz sea bass fillets, cut into 4 pieces
400g/14oz cod fillet, cut into 4 pieces
300g/10½oz halibut fillet, cut into 4 pieces
12 cockles, cleaned (discard any cockles that do not shut tightly when tapped firmly on the side of the sink)
8 cooked tiger or king prawns, shells left on
1 lemon, juice only
For the garlic toast
3 garlic cloves, peeled and left whole
200g/7oz butter, softened
1 baguette, diagonally sliced into 8-12 slices
For the aïoli
2 garlic cloves, crushed
2 free-range egg yolks
small pinch saffron strands
75ml/2½fl oz olive oil
75ml/2½fl oz vegetable oil
1 tsp white wine vinegar
salt and freshly ground black pepper
For the fish stew, heat 2 tablespoons of the oil in a wide, heavy-based saucepan over medium heat. Add the fish trimmings (or steaks) and the small prawns and season, to taste, with salt and freshly ground black pepper. Fry for 8-10 minutes, or until golden-brown all over, then remove from the pan and set aside on a plate.
Add 2 more tablespoons of oil to the same saucepan and increase the heat to high. Fry the fennel, shallots, carrot and celery for 8-10 minutes, stirring occasionally, until they begin to brown.
Stir in the tomato purée and continue to cook for 1-2 minutes. Add the chopped tomatoes, star anise, saffron and cayenne pepper and cook for a further 3-4 minutes.
Pour in the white wine and pastis and bring to the boil, scraping up any burned bits from the bottom of the pan with a wooden spoon to deglaze. Continue to boil until the liquid has reduced to a thick syrup.
Add the stocks and return the mixture to the boil. Continue to boil until the volume of liquid has reduced by one-third, about 10-15 minutes.
Remove the pan from the heat and set aside to cool slightly. Ladle the liquid into a food processor and blend to a smooth purée in batches, taking care to cover and hold down the lid of the food processor with a tea towel to avoid scalding yourself.
Strain the mixture through a fine sieve into a clean pan, then reheat over medium heat.
Season the pieces of sea bass, cod and halibut on both sides with salt and freshly ground black pepper.
Heat the remaining oil in a large frying pan over medium heat. Add the fish pieces, in batches if necessary, and fry for 1-2 minutes on each side, or until golden-brown on both sides. Add them to the strained stew.
Add the cockles to the strained stew and cook until the shells open (discard any cockles whose shells do not open during cooking). Add the cooked prawns and stir until heated through. Squeeze over a little lemon juice, then season, to taste, with salt and freshly ground black pepper. Stir in the reserved fried fish trimmings (or steaks) and the cooked small prawns.
For the garlic toast, preheat the grill to its highest setting.
