On high heat, heat some of the olive oil in a cast iron pot or wok – these types of pans just keeps the heat very well, just before smoking.
Add ¼ of the beef strips to the pan and sauté the beef strips until brown.
Remove from pan and repeat with the rest of the meat, only adding ¼ at a time. Season with salt and black pepper.
Cover rice with water, add salt and cook until done.
In the same pan/pot used for the beef strips, add a little more oil and the onions.
Add the water to de-glaze the pan, add the garlic and mushrooms and leave to cook until soft and translucent.
Add the sour cream, and mix thoroughly until incorporated. If the sauce is still a bit thin, leave to cook for another 5 minutes to reduce.
Add beef strips, stir, and season with salt and pepper if needed and serve on rice or pasta. Recipe reprinted with permission of Anina'sRecipes. To see more recipes, click here.
