Making Quick Pickled Cucumber for Fish Tacos

The British Seaside and the Rise of the Fish Taco

There is something deeply satisfying about eating fish by the sea. Whether you are huddled on a bench in Whitby with a paper of battered cod, or sitting on a Cornish harbour wall watching the gulls, the combination of salt air and crisp fish is hard to beat. But British coastal food is evolving. Alongside the traditional chippy, you will now find fish tacos popping up in beachside cafes from Brighton to the Outer Hebrides. They offer a lighter, zingier way to enjoy our superb local catch. The secret to a great fish taco is not just the fish, but the sharp, crunchy pickle that cuts through the batter. And you can make that pickle in your own kitchen in less time than it takes to drive to the coast.

Why Quick Pickling Cuts Through Battered Fish

Battered fish is rich. The batter is crisp and golden, but it is also heavy with oil and flour. Without a bright, acidic counterpart, a few bites can feel cloying. That is where quick pickled cucumber comes in. The vinegar delivers a clean, bracing sharpness that slices through the fat like a knife. The cucumber itself stays crunchy, adding texture that contrasts with the soft fish and tender tortilla. Dill, with its grassy aniseed notes, is a classic partner for fish – think of gravadlax or a dill sauce for salmon. In this pickle, it lifts the whole taco into something fresh and coastal. You do not need weeks of fermentation; a brief soak in vinegar and sugar does the job beautifully.

The Recipe: Quick Pickled Cucumber with Dill

This makes enough for four to six tacos, but you can easily double it. Use a mandoline if you have one, or a sharp knife and a steady hand. The thinner the slices, the better they cling to the fish.

• 1 large cucumber (about 300g), thinly sliced
• 1 tsp fine sea salt
• 100ml white wine vinegar or cider vinegar
• 1 tbsp caster sugar
• 1 tsp dill seeds, lightly crushed, or 2 tbsp fresh dill, chopped
• Optional: 1 small red onion, thinly sliced

Step one: Put the cucumber slices in a colander, sprinkle with the salt, and toss. Leave for 15 minutes. This draws out excess water so the pickle stays crisp rather than soggy. Step two: Rinse the cucumber briefly and pat dry with a clean tea towel. Step three: In a bowl, whisk the vinegar and sugar until the sugar dissolves. Add the dill seeds or fresh dill. Step four: Add the cucumber (and onion, if using) and toss well. Step five: Transfer to a jar, press down, and chill for at least 30 minutes. It will keep in the fridge for up to a week, though it is best within three days.

Pairing with Battered Fish: A Coastal Classic Reimagined

For the fish, use a firm white fillet – cod, haddock, or pollock from a sustainable source. Pat it dry, dust with seasoned flour, then dip in a simple batter of flour, cold beer, and a pinch of baking powder. Fry in hot oil until deep golden and crisp. Warm small corn or flour tortillas, flake in the fish, and pile on the pickled cucumber. Add a spoonful of soured cream or thick yoghurt, a squeeze of lime, and perhaps a few coriander leaves. The result is a taco that feels both British and global – the batter reminiscent of a chippy, the pickle bright and clean. It is perfect for a beach picnic, a holiday cottage supper, or a Friday night at home when you wish you were by the sea.

Coastal Travel Inspiration: Where to Enjoy This Combination

If you are travelling the British coast this summer, keep an eye out for fish tacos on menus. In Cornwall, the catch often includes hake or mackerel. In Yorkshire, Whitby haddock is legendary. Pembrokeshire offers laverbread and cockles, but also excellent bass. The Scottish west coast, from Oban to Ullapool, has langoustines and haddock. Wherever you go, you can make this pickle in a rented kitchen. Buy a cucumber from a farm shop, fresh dill from a market stall, and local vinegar. Then take your jar to the beach with some fried fish and tortillas. It is a portable feast that tastes of the sea. Even if you are landlocked, the sharpness and dill will transport you to a harbour wall.

Tips for Making It Your Own

Quick pickles are forgiving, so experiment. Swap white wine vinegar for malt vinegar for a more traditional British chip-shop tang. Add a teaspoon of yellow mustard seeds or a pinch of chilli flakes for heat. Fennel fronds work wonderfully instead of dill if you have them. A little sliced radish or shallot adds colour and bite. If you prefer a sweeter pickle, increase the sugar to 2 tbsp. To keep the cucumber extra crunchy, do not skip the salting step – it really makes a difference. Serve the pickle alongside grilled fish, burgers, or even a cheese sandwich. And remember: the longer it sits, the more the flavours mingle, but it is ready in half an hour. So next time you crave a taste of the coast, reach for a cucumber, a bottle of vinegar, and a bunch of dill. Your fish tacos will thank you.
