Well, yes. And that was done by the french, who decided to "add a bit of russian flavour" to fricassée de boeuf, and thus create the first ever dish of beef stroganoff, by adding classic russian ingredients, and bring it closer to russian taste. And then russians adopted the dish, and called it their own.
