An age-old Russian favourite, rich and full of flavour, in nine easy stepsStroganoff is a richly savoury dish of sautéed beef in soured cream named after a 19th-century count (though no one seems quite sure exactly which one). But it was only as recently as the 20th century that this age-old Russian favourite was gussied up with onions and mushrooms. Here, it has evolved again to eschew the meat altogether – and you may be surprised how little you miss it.Prep 15 min Cook 40 min Serves 4 C
