Backfisch mit Kartoffelsalat
Backfisch works when the batter is cold, the fish is dry, and the oil is steady. Miss one of those and you get a wet coat, not a crisp one.

Räucheraal
Created by
The northern smoked fish that asks for clean brining, dry skin, and patient beech smoke, not fuss: golden eel, dark rye, horseradish, and enough acid to cut the fat.

Räucheraal belongs to the north: Hamburg, Altona, Schleswig-Holstein, Lower Saxony, Mecklenburg, the places where eel came out of rivers, lakes, and the fish market before it came to the table. It's special-occasion fish because it's fatty, scarce, and bought on purpose. You don't find good eel by accident.
The regions split before the knife comes out. Around the coast and the Elbe, I want it hot-smoked whole over beech, skin lacquered gold and the flesh dark and oily under it. Some serve it warm from the smokehouse, others cool it, slice it, and put it on buttered rye with horseradish. Im Norden anders, im Süden anders: in the south they have their trout and char; eel is a northern argument.
The technique that decides it is drying before smoke. Brine seasons the flesh, but wet skin catches soot and turns bitter. Hang the eel until the surface is tacky and dry, then give it steady heat and clean beech smoke. Runter mit der Temperatur if the fat starts dripping hard. You want rendered richness, not a split, greasy fish.
Serve it plainly. Rye bread, butter, grated horseradish, cucumber salad with vinegar, boiled potatoes if it's supper. Weggeworfen wird nichts: the skin and head go into a small fish stock if you have enough bones, because the smoke will season the pot better than any cube. Nicht aus dem Glas.
Altona, now part of Hamburg, was one of northern Germany's great fish-trading and smoking centres by the nineteenth century, and its smokehouses helped make Räucheraal a city-market luxury as much as a coastal food. Eel also belonged to the wider Hanseatic fish trade, where smoking and salting let valuable oily fish travel inland before refrigeration. Today the European eel is severely threatened, so Räucheraal should be bought only from legal, traceable sources, and many northern cooks serve smoked trout or mackerel when proper eel cannot be sourced.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •Hot smoker with hanging hooks or racks
- •Probe thermometer
- •Non-reactive brining tub
- •Wire rack for drying
Instructions
- 1
Check the eel
Buy cleaned eel from a fishmonger or smokehouse source you trust, and ask where it came from. Eel is not a casual fish now; it must be legal, traceable, and handled cold. Rinse the cavity well and pat it dry, because blood and slime left on the fish turn muddy in the smoke.
- 2
Make the brine
Stir the salt and sugar into the cold water until dissolved, then add the bay, pepper, juniper, and onion. Keep the brine cold. Warm brine starts softening the surface before the salt has moved evenly through the flesh, and fatty eel punishes that with a ragged texture.
Do not overspice the brine. Eel carries its own fat and sweetness; juniper and bay should sit behind the fish, not bury it. - 3
Brine overnight
Submerge the eels in the cold brine, weigh them down with a plate, cover, and refrigerate for 10 to 12 hours. The salt needs time to reach the thick back meat, but longer than overnight makes the fish taste cured instead of smoked. Das braucht seine Zeit, but not more than that.
- 4
Dry the skin
Lift the eels from the brine, rinse briefly, and pat them very dry. Hang them on hooks or lay them on a rack in the refrigerator, uncovered, for 3 to 4 hours, until the skin feels tacky and no longer wet. This is the step that decides the dish: dry skin takes clean smoke and turns golden; wet skin catches soot and bitterness.
- 5
Start the smoke
Heat the smoker to 80C to 90C and use clean beechwood smoke. Hang the eels so air can move around them, or set them on an oiled rack with space between. Crowding traps moisture, and trapped moisture gives you dull grey fish instead of a tight golden skin.
- 6
Smoke until done
Hot-smoke the eel for 90 minutes to 2 hours, keeping the chamber steady and clean-smelling, until the skin is golden brown and the thickest part reaches at least 63C. If fat begins to pour out, runter mit der Temperatur, down with the temperature. You want the fat loosened through the flesh, not running away onto the fire.
- 7
Rest and slice
Rest the eel 20 minutes before cutting, or chill it completely if you want the firmer cold version. Cut through the skin in short sections and lift the flesh from the bone with a small knife. Work gently; good Räucheraal is rich and soft, and rough cutting turns it to paste.
- 8
Set the plate
Butter the rye bread, pile the eel beside it or on it, and serve with grated horseradish, cucumber dressed with vinegar, sugar, dill, and a pinch of salt, plus boiled potatoes if this is supper. The acid and horseradish are not decoration. They cut the fat so the second bite tastes as good as the first. Schön ist, was schmeckt.
Chef Tips
- •If you don't have a smoker, buy Räucheraal from a proper fish smoker and serve it well instead of pretending an oven with smoke salt is the same thing. Nicht aus dem Glas, and not from a bottle of liquid smoke either.
- •European eel is under serious pressure. Buy only from a legal, traceable source, and if you can't get that, smoke trout or mackerel over beech and keep the same plate: rye, horseradish, cucumber, potatoes.
- •Eel must be cooked through. Raw eel blood is not for the table, and hot-smoking is cooking, not perfuming. Use a probe thermometer and stop guessing.
- •Serve it cool or just warm, never hot and flaking apart. Warm from the smoker is a smokehouse pleasure; cold on rye is the northern table at its plainest.
- •Save skin, head, and bones if they are clean. Simmer them briefly with onion, bay, and water for a smoky fish stock, then strain. Weggeworfen wird nichts.
Advance Preparation
- •Brine the eel the night before, then dry it uncovered in the refrigerator the next morning before smoking.
- •Smoked eel keeps well chilled for 2 days, wrapped loosely in parchment and then covered. Slice it just before serving so the flesh stays clean and glossy.
- •The cucumber salad can be dressed 30 minutes ahead. Any longer and the cucumber gives up too much water, because salt always collects its debt.
