Svíčková is the dish Czech families make for weddings, name days and big Sunday lunches, and in Prague pubs it appears on the menu as the proud centre of the week. Beef is marinated for a day or two with root vegetables and spices, slow-roasted, and the vegetables are then blended into a smooth, sweet-sour cream sauce. It is always served the same way: sliced beef, a pool of sauce, bread dumplings, a spoonful of cranberry sauce, a twist of whipped cream and a slice of lemon. Many cooks under-season the sauce; it should taste clearly of vinegar, sugar and allspice, not just cream. The optional smoked bacon that flavours the vegetables is pork; leave it out and the sauce is still rich. Chef's tip: blend the sauce until completely velvety, then push it through a sieve; that silky finish is what makes svíčková special.
