Altmärkische Hochzeitssuppe
The Altmark wedding broth is a clear soup with no tricks: bones for depth, patient skimming for clarity, and small semolina dumplings that make it festive.

Eier in Senfsoße sit strongest on the eastern table, Berlin, Brandenburg, Saxony, Thuringia, the old weeknight plate with potatoes underneath and enough sauce to make the eggs matter. It is budget food, meatless food, canteen food when done badly, and a fine supper when done with care. Das ist kein Bierzelt. It is eggs, mustard, milk, stock, and potatoes, and that is enough.
The regions argue quietly over it. In the east I keep the sauce pale and sharp, with medium-hot mustard and a little vinegar or pickle liquor if the mustard is too soft. In the north you'll see dill and a cleaner sour edge. In the south the sauce is often rounder, with cream and a gentler mustard. Im Norden anders, im Süden anders, different in the north, different in the south.
The technique is simple and it decides the dish: make the roux first, cook the flour until it smells nutty but stays pale, then whisk in warm milk and stock until smooth. The mustard goes in off the heat. Boil mustard hard and you drive off its bite, roughen the sauce, and leave bitterness where there should be brightness. Nicht aus dem Glas means not a jarred sauce, not a packet. A spoon, a pan, five minutes.
Boil the potatoes in their skins if you have time, because the skin keeps the potato from drinking the pot water and turning loose. Halve the eggs so the yolks meet the sauce. Taste at the end: salt, mustard, vinegar, sugar only if the mustard needs balancing. Würzen, Fett, Salz zum Schluss. Schön ist, was schmeckt.
Senfeier became especially associated with Berlin, Brandenburg, Saxony, and the GDR household and canteen table, where eggs and potatoes made a filling meatless meal from cheap staples. German mustard has its own older centers: Düsseldorf's ABB mustard was founded in 1726, and Bautzen in Saxony became so closely tied to mustard that Bautz'ner Senf, introduced in the 1950s, became the everyday eastern jar. The dish shows how German thrift cooking often built a full meal around preserved sharpness, stored potatoes, eggs, and a sauce made in the pan.
The technique, the tradition, and the story behind every dish.

Equipment Needed
- •Medium saucepan for potatoes
- •Small saucepan for eggs
- •Heavy-bottomed saucepan for sauce
- •Whisk
Instructions
- 1
Boil the potatoes
Put the scrubbed potatoes in cold salted water and bring them up gently, then cook until a small knife slides through without forcing, about 20 to 25 minutes. Starting in cold water cooks the potatoes evenly from skin to center; drop them into boiling water and the outside softens before the middle catches up.
- 2
Cook the eggs
Lower the eggs into simmering water and cook 9 to 10 minutes, then cool them under cold water and peel. You want set yolks, not chalk; overboiled eggs bring a grey ring and a sulphur smell into a clean mustard sauce, and nobody asked for that.
- 3
Start the roux
Melt the butter in a saucepan over medium heat, stir in the flour, and cook for 2 minutes until it smells lightly nutty but stays pale. This short cooking takes the raw flour taste out without browning the sauce; brown roux belongs somewhere else, not on Senfeier.
- 4
Whisk the sauce
Whisk in the warm milk a little at a time, then the warm stock, keeping the whisk moving until the sauce is smooth and coats the back of a spoon. Warm liquid keeps the roux from tightening into lumps, and adding it slowly gives you a sauce instead of a pot of paste.
If the sauce does lump, take it off the heat and whisk hard before adding more liquid. Panic makes lumps worse; heat tightens them. - 5
Add mustard last
Take the pan off the heat and whisk in the medium-hot mustard, sharp mustard if using, vinegar or pickle liquor, salt, pepper, and only enough sugar to balance the edge. Mustard goes in off the heat because boiling dulls its aroma and can turn the sauce bitter. Erst verstehen, dann kochen.
- 6
Serve the plate
Peel the potatoes if you like, or leave the thin skins on, then halve or quarter them on warm plates. Halve the eggs and set them cut side up so the yolks catch the sauce, spoon the mustard sauce over generously, and finish with chives or parsley. Weggeworfen wird nichts: any leftover sauce goes over tomorrow's potatoes.
Chef Tips
- •Use German medium-hot mustard, the everyday kind, not a honey mustard. The sauce needs clean bite, and sweetness is a seasoning you control at the end, not the base of the dish.
- •Warm the milk and stock before they meet the roux. Cold liquid shocks the butter-flour paste and makes lumps, then you spend the next five minutes fixing what one small pan of warm liquid would have prevented.
- •Do not boil the sauce after the mustard goes in. Keep it warm, taste it, and serve. Mustard is not a spice brick; it has volatile bite, and hard heat knocks it flat.
- •Waxy potatoes hold their shape under sauce. Floury potatoes are fine if you're making mash, but for boiled potatoes on a plate they crumble and drink too much sauce.
Advance Preparation
- •The eggs can be boiled and peeled up to 1 day ahead, then kept covered in the refrigerator. Warm them briefly in hot water before serving so they don't chill the sauce.
- •The potatoes are best cooked just before serving, but leftover boiled potatoes can be sliced and warmed gently in a covered pan with a spoon of water.
- •Make the sauce fresh. A roux sauce reheats, but mustard loses its clean bite after sitting; if you must reheat it, do it gently and whisk in a small spoon of fresh mustard at the end.
