Using a heavy bottomed casserole dish with a lid, layer the onion, carrot, tomato and fennel
Add the garlic, chilli, fennel, the small bunch of parsley, thyme, bay leaf and the orange rind
Layer the fish and the shellfish on top
Grind the strands in a pestle and mortar
Add the oil and the wine and mix
Pour over the shellfish
Season generously with salt and pepper
Leave to marinade for 2 hours and then pour in the stock
You want the stock to cover the fish – you might not need all of it, and if you need more, use water
Bring to the boil with the lid on, remove the lid and boil for 12 minutes
Gently remove the shellfish and fish and place into a deep soup bowl
Strain the broth and serve over the fish and shellfish with a sprinkle of coriander
Notes
To dry a piece of orange rind: use a vegetable peeler and peel a piece of the skin off the orange without ‘grabbing’’ the pith. Dry in an oven heated to 100 Deg C for 20 minutes. Accompany with a French loaf and rouille
