Back in the seventies, beef stroganoff became massively popular in the west. But it's been around for a lot longer - at least since the middle of the nineteenth century. It's generally believed to be named after somebody in the Russian industrialist Stroganov family, although nobody seems to know who exactly. Whatever its origins, it's rich and creamy and meaty. And really easy to make.
