Rouladen

Rouladen are thin slices of beef rolled around bacon, onion and a pickle, browned and braised in a dark gravy. It's a Sunday classic in German homes, the kind of dish built around care rather than speed — turning a cheap, tough cut into something worth carving at the table.

What it actually is

Thin beef slices — traditionally top round, beaten flatter still with a mallet — are spread with mustard, then layered with bacon, chopped onion and a spear of pickled cucumber. Each slice is rolled tight and held closed with a toothpick or kitchen string, browned on all sides, then braised for a couple of hours in beef broth, often with a splash of red wine, until the meat is tender enough to cut with a fork.

The braising liquid becomes the gravy, usually thickened at the end and sometimes finished with a spoon of sour cream or crème fraîche for body.

How it's served

• Sliced or whole, gravy poured over, the toothpick removed before it reaches the table.
• With red cabbage and boiled or mashed potatoes, the standard Sunday-dinner pairing.
• The next day, often even better — the flavours settle overnight in the fridge.

Writing it on a menu

• Note the mustard in the filling and the pork in the bacon.
• Flag sulphites if you finish the gravy with red wine.
• Say what's inside the roll; bacon, onion and pickle is the classic, but regional versions swap in carrot or add a slice of ham.
• Mention that it's a slow-braised dish; it explains why it isn't a fast order, and it's worth the wait.
