Preparing a warming fisherman's stew at home

The heart of a coastal kitchen

There is something deeply comforting about a fisherman's stew. It is the kind of meal cooked in harbour-side cottages for generations, a one-pot dish that asks little and gives much. On a cool evening, when sea fret rolls in, a bowl of this stew warms you from the inside out. Its beauty lies in flexibility: firm white fish, potatoes and whatever root vegetables you have. It is not a precise recipe but a method, passed down by fishing families who made the day's catch stretch. Firm white fish is the star, but roots and potatoes are just as important, thickening the broth and adding earthy sweetness.

Choosing and preparing your fish

You want fish that holds its shape during a gentle simmer. Cod, haddock, pollock, coley and hake are excellent. Avoid oily fish like mackerel, which can overpower the broth. Look for bright eyes, firm flesh and a clean sea-fresh smell. A fishmonger will skin and fillet for you, but ask to keep bones and trimmings for a quick stock. At home, check for pin bones and remove with tweezers. Cut the fish into large chunks, roughly the size of a matchbox. Leave the skin on if you like; it adds flavour and helps pieces stay intact. If you live near a harbour, buy whatever is landed that day. Otherwise, a trusted counter will do, but ask about provenance.

Building the base: potatoes, roots and alliums

The base gives depth. Use a heavy-bottomed pan – a cast-iron casserole is ideal. Slice floury potatoes thinly and lay them in the bottom. They will break down, thickening the liquid into a lovely broth. On top, add sliced onions, leeks, carrots, swede and parsnips. A little celery or fennel adds aroma. Sweat in butter or rapeseed oil over a low heat until soft but not coloured. Add a bay leaf, thyme and parsley stalks. Pour over fish or vegetable stock to just cover. Season with sea salt and black pepper. Simmer gently, covered, until roots are tender, about twenty minutes.

• 2 large floury potatoes, sliced
• 2 onions and 2 leeks, sliced
• 2 carrots, 1 small swede, 2 parsnips, diced
• 1 bay leaf, sprigs of thyme, parsley stalks
• 500ml fish stock

Adjust to what your garden or market offers.

From plot to pot: gardening for the stew

A coastal garden can grow much of this stew. The maritime climate – mild, damp, salt-laden winds – suits certain crops. Potatoes thrive in bags or raised beds; 'Charlotte' and 'Maris Piper' are reliable. Leeks, carrots and parsnips are hardy, though taller varieties need a windbreak. Swede likes a long season and shelter. Herbs are essential: parsley, thyme and bay in pots near the kitchen door. Rosemary and sage also do well. For a true taste of the coast, use a little seaweed as mulch or liquid feed – a traditional seaside practice rich in trace elements. Harvest roots and potatoes in autumn for winter stews.

The simmer and the finish

When the roots are tender, add the fish. Do not stir vigorously or the chunks will break. Slide the fish into the simmering broth, tucking it under the surface. Poach for five to eight minutes, just until opaque and flaking. For a richer finish, stir in a splash of double cream or a knob of butter. Some cooks add a spoonful of mustard or a dash of cider vinegar for brightness. Taste and adjust seasoning. Let the stew sit off the heat for a few minutes; it will thicken slightly and flavours will meld. Scatter with chopped parsley and a little lemon zest.

Serving, sharing and a nod to heritage

Ladle into deep, warmed bowls. Serve with thick slices of crusty bread – soda bread or sourdough is perfect for mopping up. A glass of crisp cider or light ale goes well. This is a meal to share around a table while the wind blows outside. Fisherman's stew is a living piece of maritime heritage: boats coming in at dusk, families making do with the catch, gardens that fed the household alongside the sea. Leftovers keep for a day, but fish is best fresh. Reheat gently with a little stock. If you have grown even one ingredient yourself, the bowl will taste all the sweeter.
