My entire family has tweaked the original recipe so many times over the years that it has definitely become "Americanized". Then again, I guess it can't really be helped on some level. It started with the lack of Smetana.
Smetana is an Eastern European soured cream product that has the same properties as Crème Fraîche. It doesn't curdle under heat like Yogurt and "Sour Cream" do. It's also not quite as thick as Sour Cream, however, it is more sour than Crème Fraîche, thus the conundrum. So to produce the same effect, we originally mixed Sour Cream with Heavy Cream and Lemon Juice to produce a "smetana type" product. Then Crème Fraîche suddenly became available on a regular basis and a shift occurred. NOW we mix Crème Fraîche with a little Sour Cream and Lemon Juice. This works significantly better than the old way. (But in a pinch your can still mix 8 oz of Sour Cream with 2 oz of Heavy Cream and 1 tsp Lemon Juice)
Over the years we have dropped the Dijon Mustard from the recipe... Which is technically what makes it NOT Stroganov, being by definition "Beef in Mustard and Sour Cream". Though occasionally I throw it in anyway. In this family it's all about the wine, sour cream and homemade egg noodles... LOL
That is the one thing that has never changed over the years.... Homemade Egg Noodles.
While I realize that it's more traditional to serve Stroganov ("Stroganoff" in French) with crispy shoestring potatoes, I really enjoy it over noodles. It's a comfort food thing. Which is why I was so diligently making Egg Noodles yesterday to fill the freezer shelf. So I am always prepared for....
