Method

Braising eel in port and stock is a French technique that relies on the initial browning of aromatics to build the base flavour — skip this and you'll have a thin, one-note sauce. Rub the stewpan with butter and dust lightly with flour to create a stewing|roux base; this thickens the cooking liquid gently as the braise progresses, binding the fat and wine into a glossy sauce without lumps. Cut the onions small — not fine, small — so they soften completely and dissolve into the base rather than remaining as distinct pieces. Brown them over moderate heat until they show deep golden edges; this develops the umami that anchors the dish. Add the bay leaf, port wine, and stock together; the acidity of the port cuts through the richness of the eel while the alcohol burns off, leaving concentrated flavour.

Prepare the eels while the braising liquid comes to temperature. Wash and cut them into 7.5 cm lengths — eel skin holds the flesh together during cooking, so never skin them beforehand. Scatter the mushrooms into the pan (cremini or flat mushrooms work; avoid cultivated button mushrooms, which add only water), season with salt, pepper, and nutmeg — nutmeg is traditional here and bridges the savoury-sweet gap that port creates. Lay the eel pieces into the simmering liquid; they should be submerged or mostly covered. The braise takes 30–35 minutes; the eel is done when the flesh separates easily from the bone and the skin has begun to shrink slightly away from the meat. You're looking for the surface of the liquid to dimple gently, not roll — eel flesh shatters at a rolling boil.

While the eel braises, prepare croutons by cutting thick bread into triangles and frying or toasting until golden and crisp. This gives textural contrast to the soft, gelatinous flesh. Once cooked, arrange the eel pieces in a pyramid on a warmed serving dish and surround them with croutons. Strain the braising liquid and discard the solids — the sauce should be glossy and coat the back of a spoon. Pour it over the eel and serve immediately, very hot. The wine-reduction|reduction is your garnish here; it's the thing.
