...I'm sure it will be interesting and their Beef Stroganoff recipe is probably as authentic as anybody else's.
Reading in the foodtimeline.org, that recipe is derivative of a number of older recipes.
"...The last prominent scion of the dynasty, Count Pavel Stroganoff, was a celebrity in turn-of-the-century St. Petersburg, a dignitary at the court of Alexander III, a member of the Imperial Academy of Arts, and a gourmet. It is doubtful that Beef Stroganoff was his or his chef's invention since the recipe was included in the 1871 edition of the Molokhovets cookbook...which predates his fame as a gourmet. Not a new recipe, by the way, but a refined version of an even older Russian recipe, it had probably been in the family for some years and became well known through Pavel Stroganoff's love of entertaining."
