After making this, I can report it is the Best Stroganoff Ever.
This is the beef stroganoff recipe from Alice's Restaurant of Arlo Guthrie fame. My mother ate there in 1973 and managed to convince someone there to give up the recipe. The key is cooking the beef lightly so it's still rare and juicy.
2 lg onions, finely chopped
1 pint sour cream (use fancy stuff for this, it makes a difference. You could probably replace part with low fat yogurt. But don't use fat free sour cream. Just don't)
1 handful pine nuts (about 1 oz, get in bulk if possible, in packages they are ridiculously expensive)
1 lb fresh mushrooms, sliced
1 lb very lean beef, trimmed and if possible frozen for 1-2 hr before cutting
1/10th of a whole nutmeg, or 1/8 tsp ground nutmeg
A few tbsp butter or oil for cooking
Paprika, salt, and fresh ground pepper to taste
Finely chop onions and saute at least 20 minutes until clear. Add sliced mushrooms and saute till barely soft. Remove from pan.
Slice meat very thin (1/4" or less), in 1" by 2" pieces. Partially freezing before cutting helps get good thin slices.
Add more butter or oil to pan. Recipe says add paprika here, but I added it with the sour cream because I was afraid of burning. Sear both sides of meat quickly, on a high flame. Use
tongs (not fork) to turn pieces of meat individually; try not to let them touch one another (fork piercing or touching make juices run out...). Do 8 or 10 slices at a time: put slices in pan with one hand, turn and remove with other... set aside in a dish. Goal is that they still be
rare.
Return mushrooms and onions to pan. Add meat, sour cream, and pine nuts. Use medium-low heat; don't let it boil.
Add fresh grated or ground nutmeg, paprika if you didn't already, salt, and "lots" of freshly ground pepper. Stir until combined, and cook only until everything is heated through.
Serves 4-6. Serve over egg noodles, rice, orzo, or fresh dumplings (recipe I posted last week).
Variations: add red wine to mushrooms & onions before meat goes in. Tomato paste, garlic or dill can be added. Poppy seeds instead of pine nuts is another option.
