Jellied eels, cold set eel in its own stock: chunks of pale eel suspended within a clear, faintly amber, wobbling jelly in a small white bowl, a scatter of chopped parsley visible within the set.

Eels were once so abundant in the Thames and the River Lea that London's poor caught them independently of the Dutch trade that also supplied Billingsgate from at least 1412. The dish itself, chopped eel simmered in vinegar-seasoned water or stock, then cooled so the fish's own gelatinous skin and bone set a natural jelly, is genuinely old East End food. What this chapter will not do is present it uncritically. European eel is Critically Endangered, its numbers down 90 to 98% since the 1970s, and a 2023 UCL and Exeter DNA study of UK jellied eel products found most sampled contained European eel DNA, with trade patterns consistent with illegal trafficking somewhere upstream. This is not a detail to soften for the sake of a good story.

by London

London's other great fish trade, eels, has an even more serious modern reckoning attached to it, and this chapter will not soften it. European eel is Critically Endangered on the IUCN Red List, its numbers reaching Europe down somewhere between 90 and 98% since the 1970s, its recruitment at roughly 1% of 1970s levels. It sits on CITES Appendix II; the EU bans its export outside the bloc, yet it remains legal to fish and eat within Britain, a genuine paradox. Glass-eel trafficking is now assessed as one of the world's most lucrative wildlife crimes, an EU-wide law enforcement operation running since 2015 has seized over 100 tonnes, some 327 million eels, and a 2023 UCL and Exeter DNA study of jellied eel products sold in Britain found most contained European eel DNA, with import and export patterns consistent with illegal trafficking somewhere in the supply chain. The dish this trade built, jellied eels, is treated in full below, and this history is why.

Read the history

As tradition built it

Serves 4. About 45 minutes, plus setting.

Ingredients

1kg eel, cleaned and cut into chunks
600ml water
2 tbsp white wine vinegar
1 onion, sliced
to taste a few peppercorns, a bay leaf, salt
to taste a squeeze of lemon

Method

Bring the water, vinegar, onion, peppercorns, bay and salt to a simmer.
Add the eel and poach gently, 15 to 20 minutes, until just cooked through and no longer translucent.
Lift the eel into serving bowls or a single dish.
Strain the cooking liquid, adjust seasoning with a little lemon, and pour over the eel.
Cool, then chill for at least 4 hours, until fully set into a firm jelly.
Serve cold, with vinegar or white pepper alongside.

What a modern chef changes

The species question answered honestly before the technique question is asked at all.

No numbered rung; this is a sourcing discipline, not a kitchen one

Method

Buy Lough Neagh eel specifically, PGI-protected and managed since 2011, and ask for it by name, rather than an unlabelled "eel" that carries no comparable guarantee, since this is currently the best-documented least-bad named UK source for the species.
Treat this as an occasional dish, not a weekly one, and say so to anyone you serve it to. The most honest modernist move available here is restraint, not technique.
If serving it, poach gently and briefly rather than at a hard simmer, watching for the point the flesh just turns opaque, since overcooked eel toughens fast and there is little reason to compound a sourcing compromise with a cooking one.
