Bratensoße (Dunkle Bratensauce)
A proper Bratensoße begins with the brown bits in the pan, not a packet: bones roasted dark, wine scraped clean, stock reduced until it coats the spoon.

Stale bread and beef broth make the body; raw fresh horseradish gives the bite. Boil it after that and you've cooked the whole point out of the sauce.
Meerrettich-Semmelsoße belongs beside boiled beef, especially in the south and east: Franconia, Bavaria, Swabia, and over the Austrian line where they call it Semmelkren. It sits well on a Sunday table and it has a place at Christmas when one pot gives you sliced beef, vegetables, broth, and the sauce that ties it together. This is winter-root cooking. A stale Semmel, a piece of Kren, the broth from the meat. Weggeworfen wird nichts.
The regions argue in the usual useful way. In Franconia and Bavaria they say Kren for Meerrettich, horseradish, and they like the sauce direct, pale, and sharp. Farther north, Meerrettichsoße often starts as a white roux with milk or cream, smoother and softer. Austria leans hard into the bread and beef broth. Im Norden anders, im Süden anders. Das ist kein Bierzelt.
The technique is simple and unforgiving: simmer the bread base first, then take the pot off the heat before the fresh-grated Meerrettich goes in. Boil the root and its heat leaves the sauce, so what should bite cleanly turns dull and bitter. Stir it in raw and the sauce wakes up the boiled beef instead of burying it.
Watch the thickness before you touch the root. Bread needs a few minutes to swell, and an old roll thickens differently every time. Loose sauce gets another minute; tight sauce gets a splash of broth. Erst verstehen, dann kochen.
Horseradish cultivation in Middle Franconia around Baiersdorf near Erlangen is documented from the late Middle Ages, and the area became known as Krenland, horseradish country, with Kren still the Franconian and Bavarian word for the root. The sauce grew beside boiled beef dishes such as Tafelspitz and Krenfleisch, where the meat pot supplied both the sliced beef and the broth for the bread-thickened sauce. Using stale Semmel as the thickener records an older household economy: yesterday's roll became body for the sauce before flour roux and cream took over in many northern versions.

Tear the stale Semmel, the old bread roll, into small rough pieces and put it in a saucepan with the milk and beef broth. Let it stand ten minutes before the heat goes on. Stale bread drinks the liquid and thickens cleanly; fresh bread turns pasty and sweet, and then you've made nursery food, not sauce.
Set the pan over low heat and simmer, stirring and pressing the bread with a whisk, until the pieces collapse and the sauce turns thick and spoon-coating, about 8 to 10 minutes. Keep it gentle. A hard boil catches milk on the bottom and tightens the bread into lumps; low heat lets the starch swell evenly.
Whisk in the butter until the sauce looks satin rather than dull, then season with sugar, nutmeg, white pepper, and only a little salt. Salt waits because the beef broth may already carry enough. Würzen, Fett, Salz zum Schluss, the last tasting is where the sauce becomes yours.
Peel only the piece of Meerrettich you need and grate it fine at the last minute. Do it near an open window if the root is fierce. The sharp heat is volatile, and it fades while grated root sits on the board; grate early and the bite is gone before the beef is sliced.
Pull the pan off the heat, stir in the grated horseradish and the lemon juice or vinegar, and taste at once. Do not boil it now. Heat drives off the mustard bite and leaves a flat, cabbagey bitterness, while acid steadies the sharpness and keeps the sauce clean. Nicht aus dem Glas. The jar has already lost the fight.
Serve the sauce immediately with boiled beef, Tafelspitz, or Franconian Krenfleisch, with boiled potatoes to catch what runs. It should be thick enough to coat a slice but loose enough to pour. Grate a little fresh horseradish over the top if the table likes it sharp. Schön ist, was schmeckt.

Plain mushrooms browned hard, then loosened with stock and cream. The sauce is mild, pale, quick, and honest, made for Schnitzel, Spätzle, or a weeknight pork cutlet.

The cold sauce for the winter hunting table: ruby redcurrant jelly, port, orange, mustard, and ginger, stirred smooth the day before so sharp and sweet sit together.

Berlin's kiosk sauce is won in the pan before the sausage is even cut: onions softened, tomato paste browned, curry bloomed in fat, then vinegar and salt at the end.
