The fish stew base can be made two days in advance, and I would highly recommend this as the flavours intensify. It can also be frozen in batches.
- Put the dried mushrooms into 150ml of boiling water for at least 15 minutes to re-hydrate.
- Chop all the vegetables, medium sized, not that important as we are going the blend the sauce.
- In a heavy based pan on a medium-high heat, add the olive oil, then once hot add the onions, leek, fennel, celery & carrot. Sweat off for at least 5-10 minutes with no colour.
- Then add the chopped tarragon, 2 of the garlic cloves chopped, turn the heat up, and add the pastis/Pernod and dry vermouth for 1 minute. This will deglaze the pan and give it a scrape with a wooden spoon.
- Add the tinned tomatoes, the soaking porcini mushrooms and it’s liquid, add the fish stock and a good pinch of salt and pepper. Bring to books and simmer for 20 mins to reduce by half. Once reduced, allow to cool for 5 minutes then blend with a stick blender or in a blender. The sauce should have the consistency of single cream and not be too thick. You can always add a little more fish stock if required to thin it out. It will keep in the fridge for two days or freezer for 1 month.
- Chop the remaining two garlic cloves and the parsley, add together and mix in the capers. Put to one side for garnishing the stew
- In a medium pan boil the potatoes in water with the saffron and a pinch of salt for 10 mins or until tender.
- Now for the fish. Is shallow large pan with a fitting lid, add the olive oil, then add the fish, skin side down, the clams/mussels and the white wine, put the lid on and cook, giving a little shake now and again until the mussels/clams have opened, discard any that don’t.
- Now add the hot fish stew base along with the cooked lobster, squeeze of lemon, put the lid back on and cook on a medium heat for 3-4 minutes.
- Drain the potatoes and add a knob of butter along with the chopped garlic, parsley and caper mix. Give it a stir.
- Ladle into warm bowls and place 3-5 butter potatoes on top. Drizzle with some good extra virgin olive oil.
