Bouillabaisse Toulonnaise

4 T olive oil

4½ oz (125 g) fennel, sliced

2 red onions, chopped

1 tsp sea salt

1 T tarragon, chopped

½ tsp black pepper

Fish heads, bones and offcuts

2.2 lb (1 kg) tomatoes, roughly chopped

2 T tomato purée

1 pinch saffron threads

1 lemon, juiced

2 T butter

3 egg yolks

Salt and pepper

½ lemon, juiced

Pinch saffron

Pinch cayenne pepper

6¾ fl oz (200 ml) olive oil

2 cloves garlic, crushed

7 oz (200 g) salmon

7 oz (200 g) pollock

7 oz (200 g) monkfish

1 lb (450 g) mussels, scrubbed, beards removed

Heat the olive oil in a large pan over medium heat. Add the fennel and cook for 3 to 4 minutes without it coloring, then add the red onion, sea salt, tarragon and black pepper. Add the fish bones and offcuts and the tomatoes, then cover with water. Bring to a simmer, skimming off any residue that rises to the surface. Add the tomato purée and saffron and bring back to a simmer. Cook for about 1½ hours, or until it has reduced by about a third. Sieve the broth, pressing down the contents of the sieve with a ladle to extract as much liquid as possible, then add the lemon juice and whisk in the butter. Check the seasoning, then cool and refrigerate until needed.

Whisk the egg yolks with the seasoning, lemon juice, saffron and cayenne pepper. Slowly add the oil in a thin stream, whisking continuously, then stir in the garlic. Add a little warm water if it is too thick. Set aside until needed.

Bring the reserved broth up to a simmer, then add all the fish. Poach until just tender, adding the firmest fillets first.

Remove fish from broth and place on a serving platter. Ladle broth over fish; serve with rouille on the side and some garlic croutons.
