Paling in 't Groen

Fresh eel gently poached in a vivid green sauce of spring herbs — chervil, sorrel, parsley and spinach — a river dish of the Scheldt borderlands.

In late spring, when the riverbanks along the Scheldt turn green and the first tender herbs come up, the borderland kitchens of Zeeland and Flanders make paling in 't groen — fresh eel poached in a vivid, grassy sauce of whatever leaves the season gives. It is one of the loveliest dishes of the low country's rivers, the deep richness of the eel set against the sharp, bright green of sorrel and chervil, and it belongs equally to both sides of the border.

A dish of the borderlands

Eel thrives in the brackish tidal rivers of the southwest, and paling in 't groen grew up where those waters run — the old lands of the Scheldt shared between the Netherlands and Belgium. The dish is a seasonal one, tied to spring, when sorrel and chervil are young and the herbs are at their most fragrant. It is a rare example of Dutch cooking reaching for a whole handful of fresh herbs, and the combination is old and deliberate.

Sharp green against rich fish

The genius of the dish is balance. Eel is among the fattiest of freshwater fish, and left alone it can be cloying; the herb sauce exists to cut it. Sorrel is the key, its lemony acidity slicing through the richness, backed by the anise sweetness of chervil and the freshness of parsley and chives. The herbs go in late so they stay green and grassy rather than stewing dull, and a liaison of egg yolk and lemon draws everything into a glossy coat.

Sorrel is what makes the dish sing — its lemon-sharpness is the exact foil the rich eel needs.

Traditionally it is often eaten cold, when the eel's natural gelatin sets the green sauce into a light, fresh jelly around the fish. Hot or cold, keep the heat gentle once the yolks go in, and let the vividness of the herbs carry it. Given how fragile eel stocks now are, source responsibly and treat it as the seasonal luxury it is.

From the kitchen

“Keep the sauce below a simmer once the yolks go in — the moment it boils it will curdle into scrambled threads.”

Ingredients

Serves 4

The eel

800 gfresh eel — cleaned, skinned, in 5 cm pieces
40 gbutter
150 mldry white wine
150 mlwater or light stock

The green herbs

50 gsorrel — shredded
30 gchervil — chopped
30 gflat parsley — chopped
50 gspinach — shredded, for colour
1 tbspchives — snipped

To finish

2egg yolks
1 tbsplemon juice
to tastesalt and white pepper

Method

1
Sweat the eel
Melt the butter in a wide pan and turn the eel pieces gently in it over low heat for a few minutes, without browning. This firms the flesh and lets it begin to give up its gelatin, which will body the sauce later.
2
Poach in wine
Pour in the wine and water, bring to a bare simmer, and poach the eel gently for about 10 minutes until just cooked through. Keep it low — eel is rich but delicate, and a hard boil would toughen it and cloud the liquid.
3
Wilt the herbs
Add the sorrel, chervil, parsley, spinach and chives and stir just until they collapse into the liquid and turn it vivid green. Add them late so their fresh, grassy flavour and colour stay bright rather than stewing to khaki.
4
Thicken with yolks
Whisk the egg yolks with the lemon juice, stir in a ladle of the hot liquid to temper them, then pour back into the pan off the heat. Warm gently, never boiling, until the sauce thickens to a glossy, herb-flecked coating.
5
Serve warm or cold
Season and serve. Paling in 't groen is good hot with bread or boiled potatoes, but is traditionally often eaten cold, when the gelatin sets the sauce lightly around the eel into a fresh, green jelly.

Questions from the kitchen

Where does paling in 't groen come from?+

It is a river dish of the Scheldt borderlands shared between Zeeland and Flanders, where eel from the tidal rivers met the spring herbs of the marshes. It is as much a Flemish classic as a Dutch one.

Which herbs are essential?+

Sorrel is the signature, bringing a lemony sharpness that cuts the eel's richness; chervil and parsley are near-standard. Beyond that, cooks use whatever green herbs the season offers — spinach is common for colour.

Can I make it without egg yolks?+

Yes. The eel's own gelatin thickens the sauce somewhat, and you can lean on that, but the yolks give the classic glossy, lightly set finish. Add them off the heat to be safe.
