Westfälisches Zwiebelfleisch

Ingredients

Equipment Needed

• •Heavy 5 to 6 litre stockpot
• •Fine sieve
• •Wide sauté pan or saucier
• •Sharp slicing knife

Instructions

1. 1

   Build the broth

   Put the beef, bones if using, carrots, celeriac, leek, halved onion, bay, peppercorns, juniper, salt, and cold water into a heavy pot. Bring it up slowly until the surface barely trembles, skimming the grey foam as it rises. The slow climb gives you a clean broth for the sauce; a rolling boil clouds the liquid and tightens the meat before it has had time to soften.

   Brown the cut sides of the halved onion in a dry pan before it goes into the pot if you want a deeper broth colour. Stop at dark gold, not black, because bitter onion has no place in this sauce.
2. 2

   Cook it quiet

   Keep the pot just below a boil for 2 1/2 to 3 hours, partly covered, until a skewer slides into the beef with little resistance. Add a little water if the meat rises above the liquid. Do not hurry it. Das braucht seine Zeit. Hard boiling makes stringy beef; quiet cooking loosens the collagen and leaves you meat that slices cleanly.

3. 3

   Rest and strain

   Lift the beef into a shallow dish and cover it with a ladle of broth so the surface does not dry while you make the sauce. Strain the broth and keep it hot. Weggeworfen wird nichts: the bones and vegetables have done their work, and the broth they gave you is the base of the sauce.

4. 4

   Sweat the onions

   Melt the butter or beef fat in a wide pan, add the sliced onions with a pinch of salt, and cook them over low heat for 15 to 20 minutes until soft, glassy, and pale gold. Stir often and keep the heat down. Browned onions taste of roast gravy; this sauce needs onion sweetness without the dark edge.

5. 5

   Thicken the sauce

   Sprinkle the flour over the onions and stir for 2 minutes, until the flour smells nutty and no dry patches remain. Pour in the hot strained broth a ladle at a time, stirring hard after each addition, then simmer gently for 10 to 12 minutes. Flour needs that time to lose its raw taste, and adding the broth slowly keeps the sauce smooth instead of lumpy.

6. 6

   Sharpen and serve

   Stir in the mustard, vinegar, 1 teaspoon sugar, and white pepper, then taste before adding more sugar or salt. Mustard and vinegar go in near the end because hard cooking dulls their bite, and this sauce should be sweet-sour, not sweet alone. Slice the beef across the grain, lay it on a warm platter, spoon the onion sauce over it, and finish with parsley if you use it. Serve with Salzkartoffeln, boiled potatoes, and something pickled.

Chef Tips

• •Buy Tafelspitz with a clean fat cap if you can. The fat protects the meat in the pot and gives the broth body; if you use brisket, choose a flat piece with some cover fat, not a dry trimmed block.
• •The sauce should be pale gold, not brown. Once the onions take colour, they pull the dish away from Münsterland and toward ordinary roast gravy.
• •Use medium-hot German mustard, not a sweet yellow squeeze bottle. The mustard is seasoning and structure, and it needs vinegar behind it to keep the sauce awake.
• •Serve the sauce generously. Zwiebelfleisch is not sliced beef with a polite spoonful beside it; the onion sauce is the reason the dish exists.

Advance Preparation

• •Cook the beef one day ahead and chill it covered in its strained broth within two hours. Meat kept under its own broth stays moist, and the fat lifts off cleanly the next day.
• •Make the onion sauce up to one day ahead, but hold back a spoon of vinegar and a little mustard for reheating. Bright seasoning fades in the refrigerator, so wake it up at the end.
• •Leftover broth becomes soup, lentils, or the next pan sauce. Nicht aus dem Glas, especially when the good broth is already sitting there.
