A mid-century steakhouse showpiece — supposedly named for Diana the huntress — finished tableside in flames by tuxedoed waiters. Underneath the theater it's the fundamental pan-sauce pattern: sear, deglaze, enrich, mount. Thin-pounded steak keeps it in true retro fast-cooking style.

Ingredients

  • 2 sirloin or fillet steaks, pounded to ~1.5cm (½–¾") thick about 200g (7 oz) each
  • 1 tbsp neutral oil
  • 2 tbsp butter, divided
  • 1 large shallot, finely minced
  • 1 garlic clove, minced
  • 150g (5 oz) mushrooms (optional), thinly sliced traditional in many versions
  • 60ml (¼ cup) brandy or cognac
  • 1 tsp Dijon mustard
  • 1 tsp Worcestershire sauce
  • 125ml (½ cup) beef stock
  • 125ml (½ cup) heavy cream
  • Salt and black pepper, to taste
  • Parsley or chives, chopped, to serve a small handful

Method

  1. Dry the steaks well, season generously. Heat the oil with 1 tbsp butter in a heavy skillet over high heat until just smoking.
  2. Sear the steaks hard and fast — per side for medium-rare at this thinness. Remove to a warm plate; they'll finish with carry-over heat.
  3. Lower to medium. Add remaining butter, then shallot, garlic, and mushrooms; cook until the mushrooms' moisture is gone and they're golden, .
  4. Take the pan off the heat. Add the brandy, let it warm a few seconds, then ignite it (long match or tilt to the gas flame) and swirl until the flames die. No flambé? Just simmer it down — you lose theater, not much flavor.
  5. Back on the heat: stir in mustard and Worcestershire, add stock, and boil hard until reduced by half, scraping up the fond.
  6. Add the cream and any resting juices from the steaks; simmer to a sauce that coats a spoon. Taste — it should be punchy.
  7. Return the steaks just to warm through ( a side), spoon over the sauce, finish with herbs.

Why it works

  • Thin steak is the point. Pounding gives maximum crust-to-interior ratio and keeps total cook time inside the sauce-making window — the dish was designed to be executed start-to-finish in one pan in front of the diner.
  • Off the heat before the brandy. Pouring spirits into a pan over an open flame invites the flame up the bottle stream. The flambé itself mostly burns surface alcohol; the deeper purpose of the brandy is deglazing the fond — which is why skipping ignition barely matters.
  • The fond is the flavor. Everything the sear stuck to the pan dissolves into the stock reduction; a nonstick pan produces a flat sauce because nothing stuck.
  • Resting juices go in the sauce. They're concentrated seasoning; pouring them back in (step 6) is free flavor most cooks throw away.
  • Classic pitfall: adding cream before reducing the stock. Cream caps how hard you can boil the sauce (it splits under long hard reduction), so build the concentration first, enrich last — the same order as every pan sauce, cf. steak au poivre, which is this dish minus mustard-Worcestershire, plus peppercorns.

Wine pairing

A Merlot-led Bordeaux — Saint-Émilion or Pomerol. The brandy-mustard-cream sauce wants a red with plush, supple fruit rather than aggressive tannin, and Merlot's roundness slots into the cream while still meeting the beef. A Southern Rhône blend (Grenache-forward, spicy but soft) is the more affordable route to the same effect.
