There is a moment, just before you step into a fishmonger’s, that has been part of the British street since time immemorial: the moment you decide whether the smell is “the fish” or “the fish’s problem”. It is a negotiation you have been having with your own nose since you were six years old, and you have never once won it clearly. You go in anyway, because the alternative is a cod fillet from the supermarket freezer, which is a perfectly respectable piece of fish and about as exciting as a queue at the post office.
The fishmonger’s counter is one of those rare British institutions that still runs on eye contact. There were around 7,000 to 8,000 of them at the trade’s heyday in the late 1940s, and the number is a fraction of that now — a tide that has mostly decided not to come back — but the counter itself is unchanged: a slab of stainless steel, a scale that looks like it survived the Blitz, and a man or woman who will look you dead in the eyes and say “nice piece”, at which point you nod, because arguing is a luxury you have not budgeted for. The City of London even has a livery company for the trade — the Worshipful Company of Fishmongers — which has been looking after the business of selling fish since the Middle Ages, which is longer than most British institutions manage without a scandal. The glass case is a two-way mirror: you are choosing fish, and the fishmonger is deciding whether you are the sort of person to get a free bit of lemon. You will both know the answer by the till.
Here is why you bother: a fresh cod fillet is a different animal from a frozen one in the way a handwritten letter is different from an email. The flesh is firmer, the flavour is cleaner, and it bakes in twenty minutes instead of an hour and a half. This dish is cod with a butter, caper and lemon crust — the fishmonger’s idea of a nice piece, done the way he would have done it if he’d been allowed a kitchen. The fishmonger’s counter and the oven have one thing in common: both reward you for being decisive, and both punish you for hovering.
Ingredients
- 4 fresh cod fillets, about 150g each — the “nice piece” from the counter. If you can’t get to a fishmonger’s, the fresh-fish section of the supermarket will do; just don’t say you didn’t prefer the other one
- 3 tbsp unsalted butter, softened
- 3 tbsp fresh breadcrumbs (or a handful of stale bread blitzed in the food processor — the fishmonger will not judge)
- 1 tbsp capers, roughly chopped
- 1 lemon — half zested, half cut into wedges
- 1 garlic clove, grated
- A few sprigs of flat-leaf parsley, chopped (optional, but it makes the case look expensive)
- Salt and black pepper
- A knob of butter or a splash of olive oil for the tray
Method
- Heat the oven to 200°C (fan 180°C, gas 6). This is the only part of the recipe that expects you to be on time. The fishmonger will have your fillet wrapped before you have finished deciding, and the oven, like the fishmonger, will be there when you get to it.
- Beat the butter together with the breadcrumbs, capers, lemon zest, garlic and parsley until it is a stiff, slightly lumpy paste. It should look like something the fishmonger would wipe the counter down with, which is to say: nobody is being fussy about it.
- Lay the cod fillets skin-side down on a lined baking tray and season with salt and pepper. If they came from the counter they will be slightly different thicknesses. This is not a defect, it is a style — the fishmonger has been choosing by eye for longer than you have been alive, and he is not wrong.
- Spread the butter and crumb mix over the top of each fillet. Don’t press it in; lay it on the way the fillet was laid on the counter — confidently, without ceremony, and with the air of someone who has done it four hundred times before lunch.
- Bake for 15–20 minutes, until the flesh turns opaque, flakes with a fork, and the topping is golden. The cod will look done slightly earlier than you think it is. Trust the fork: the fishmonger tells you it’s a nice piece, the fork tells you it’s a cooked one.
- Finish with the lemon wedges and a scatter of the capers from the topping, and serve with something starchy — new potatoes, a proper mash, a handful of green beans. The lemon does the job the fishmonger’s “nice piece” did: it makes you certain of what you bought.
For a vegetarian version, swap the cod for thick slices of cauliflower — a whole cauliflower, sliced across, thick as a book — with a little extra oil on the tray and 25–30 minutes in the oven. The same butter and crumb topping works, and nobody at the table will be any the wiser. Except the ones who know.
Leftovers? There are no leftovers. That’s the point of a nice piece — it doesn’t hang around. If the fishmonger is right, and he usually is, you’ll be back tomorrow; and in Britain, in food, in football, in most things, that is rarer than it should be.
