Simple Fish Stew Using Local Market Produce

A Warming Pot for Blustery Days

When the wind turns and the sea goes slate-grey, the coast has its own kind of comfort food. This simple fish stew is the sort of supper a cottage kitchen does best: one pot, a short list of ingredients, and a bowl of something creamy, herby and deeply savoury at the end of it. Forty minutes, most of it hands-off simmering.

The other pleasure is where it comes from. Buy from the market or the harbour counter and you are buying fish landed that morning, from a fishmonger who will tell you what is swimming well. Choosing pollock or coley over a heavily fished favourite is a small decision that keeps money and flavour in the community on your doorstep.

What to Look For at the Market

Fish for a stew must hold its shape but flake under a spoon. Anything too delicate dissolves; anything too dense sits there stubbornly.

• Best choices – haddock, cod, pollock, coley or hake, cut into thick chunks rather than thin tails.
• Leave out – oily fish such as mackerel, which overpowers a creamy broth. Salmon, too, is better elsewhere.
• How much – about 1.2kg of skinned, boned fillets feeds four generously.
• Ask for offcuts – fish frames and trimmings simmered for twenty minutes with a bay leaf and a strip of lemon peel make a far better stock than a cube.
• Vegetables – small, firm leeks with plenty of white, and floury potatoes. Waxy ones hold their shape but give a thinner broth.

The Ingredients

For four people you will need:

• 1.2kg mixed white fish fillets, cut into large chunks
• 700g floury potatoes, peeled and cubed
• 2 medium leeks, sliced and rinsed well
• 40g unsalted butter
• 1 tbsp plain flour
• 500ml fish stock
• 250ml whole milk
• 150ml double cream
• 1 bay leaf, a few sprigs of thyme, a handful of flat-leaf parsley
• 1 tsp Dijon mustard and the finely grated zest of half a lemon
• Salt, white pepper and a grating of nutmeg

Making the Stew

Use a wide, heavy casserole so the fish can sit in a single layer. Everything happens in this one pot.

• Soften the leeks. Melt the butter, add the leeks and a pinch of salt, and cook gently for eight to ten minutes without colouring. Add the thyme and bay.
• Build the base. Stir in the flour, cook for a minute, then add the stock a little at a time. Add the potatoes and simmer for twelve to fifteen minutes until a knife slips in easily.
• Add the cream. Pour in the milk and cream, stir in the mustard, lemon zest and nutmeg, and bring back to a bare simmer. Season well.
• Poach the fish. Lay the chunks on top, press them down gently, cover and cook for five to six minutes. Do not stir, or the fish will break up.
• Finish. Take the pot off the heat, scatter over the chopped parsley, and rest for five minutes with the lid on.

Swaps, Tweaks and Store-Cupboard Comforts

Made a couple of times, this becomes a template rather than a recipe.

• Smoky depth – 100g chopped smoked bacon or a spoonful of smoked paprika, added with the leeks.
• Shellfish – a handful of mussels or prawns in the last three minutes makes it celebratory.
• Without cream – extra milk and a knob of butter, or a spoonful of crème fraîche at the end.
• Herbs – dill, chives or tarragon all work. Add soft herbs at the end, never at the start.
• Thicker – mash a few cooked potatoes against the side of the pot before the fish goes in.

Serving It on a Coastal Evening

Ladle the stew into deep bowls and serve with thick slices of buttered sourdough. A sharp green salad with a mustardy dressing cuts the cream, and a dry white or a light chilled red does the same. Snip a few chives or parsley straight from the windowsill pot — the sort of finishing touch that makes a plain supper feel considered.

Leftovers keep for two days in the fridge, though the potatoes will drink the broth overnight; loosen with a splash of milk when you reheat. It does not freeze well, because the cream separates and the fish turns grainy, so cook only what you plan to eat. Make it on an evening when the rain comes sideways off the sea, and it will taste like exactly the right thing to have made.
