HOW TO MAKE A FISH BROTH RECIPES

Steps:

• 1. It’s worth trying to get hold of saffron for this one – it’s available from most delis and good supermarkets. It’s not cheap, but bear in mind you won’t need much at all to spice up a dish. Make sure you use a wide pan so all the fish is in contact with the tomatoey broth. If you haven’t got one, try using a high-sided roasting tray instead, with another tray as a lid.
  2. To make the saffron aïoli, smash a clove of garlic, a tiny squeeze of lemon juice, and the saffron (if using) with a small pinch of salt in a pestle and mortar or a Flavour Shaker™ until it turns into a mush. Add a tablespoon of mayonnaise and pound again. Stir in the rest of the mayo. Taste and season with a little more lemon juice, salt and pepper.
  3. Give the mussels and clams a good wash in plenty of clean cold water and scrub any dirty ones lightly with a scrubbing brush, pulling off any beardy bits. If there are any that aren’t tightly closed, give them a sharp tap. If they don’t close up, throw them away.
  4. Heat a large, wide saucepan or stewing pot and pour in a splash of olive oil. Slice up the rest of the garlic and fry it in the oil until lightly golden. Add the wine and the tomatoes and the basil stalks and bring to the boil. Simmer gently for 10 to 15 minutes, until the liquid has reduced a little.
  5. Add all your fish and shellfish in a single layer and season with salt and pepper. Push the fish down into the liquid and put the lid on. Cook gently for about 10 minutes or until all the clams and mussels have opened and the fish fillets and langoustines or prawns are cooked through. (Discard any clams or mussels that don’t open.)
  6. Toast the bread on a hot griddle pan and get out the serving bowls. Put a piece of toast in each bowl and ladle the soup over the top, making sure the fish is divided more or less evenly. Top each bowl with some fennel tops, basil leaves, a drizzle of extra virgin olive oil and a big blob of saffron aïoli.

Steps:

• To make the croutons heat oven to 200C/180C fan/gas 6. Lay the slices of bread on a flat baking tray in a single layer, drizzle with olive oil and bake for 15 mins until golden and crisp. Set aside – can be made a day ahead and kept in an airtight container.
• Use a layer of the green part of the leek to wrap around and make a herb bundle with the thyme, bay, parsley stalks, orange peel and chilli. Tie everything together with kitchen string and set aside.
• Heat the oil in a very large casserole dish or stock pot and throw in the onion, sliced leek and fennel and cook for about 10 mins until softened. Stir through the garlic and cook for 2 mins more, then add the herb bundle, tomato purée, star anise, Pernod if using, chopped tomatoes and saffron. Simmer and stir for a minute or two then pour over the fish stock. Season with salt and pepper, bring to a simmer, then add the piece of potato. Bubble everything gently for 30 mins until you have a thin tomatoey soup. When that piece of potato is on the brink of collapse, fish it out and set aside to make the rouille.
• While the broth is simmering make the rouille by crushing the garlic, chilli and saffron with a pinch of salt in a mortar with a pestle. Mash in the cooked potato to make a sticky paste then whisk in the egg yolk and, very gradually, the olive oil until you make a mayonnaise-like sauce. Stir in the lemon juice and set aside.
• Once the chunky tomato broth has cooked you have two options: for a rustic bouillabaisse, simply poach your fish in it along with the mussels, if you're using (just until they open) and serve. For a refined version, remove the herb bundle and star anise. Using a handheld or table-top blender, blitz the soup until smooth. Pass the soup through a sieve into a large, clean pan and bring to a gentle simmer. Starting with the densest fish, add the chunks to the broth and cook for 1 min before adding the next type. With the fish we used, the order was: monkfish, John Dory, grey mullet, snapper. When all the fish is in, scatter over the mussels, if using, and simmer everything for about 5 mins until just cooked and the mussels have opened.
• Use a slotted spoon to carefully scoop the fish and mussels out onto a warmed serving platter, moisten with just a little broth and scatter over the chopped parsley. Bring everything to the table. Some people eat it as two courses, serving the broth with croutons and rouille first, then the fish spooned into the same bowl. Others simply serve it as a fish stew. Whichever way you choose the rouille is there to be stirred into the broth to thicken and give it a kick.
