I haven't seen a duplicate of this. My father has made stroganoff this way since I was a little kid and now I make it. If you don't have a pressure cooker, cook your cubes however desired be it fry or boil or whatever you like, but using the pressure cooker helps keep them nice and tender. this recipe can be adapted for a slowcooker, I don't know exact times because I used the pressure cooker, but give it at least 6-8 hours depending on the size of your beef cubes - make sure they are cooked through. 8 oz of sour cream is a minimum, thats what I usually mix into it, and then I serve extra on the side. This is one meal there are never leftovers for. I'm sorry I have no other words to describe the "jiggler" on top of the cooker, you will see when you start to cook on high heat, the difference between the "slow steady" jiggle and the "crazy" jiggle... a better word would almost be a violent jiggle. If your extremely unsure, then just don't cook your meat this way or use hamburger meat instead.
This is a meal that we don't really mind not being too meaty, in fact most meals I try to skimp on meat to save money - so if you'd like to add more meat feel free.
