BEEF STROGANOFF (FROM THE "OLD" RUSSIAN TEA ROOM)

Steps:

• Cut meat into 1/2 inch thick slices. Place between sheets of waxed paper and pound until its 1/4 inch thick (be careful not to tear meat). Cut pounded meat into 2x1/2 inch slices. Sprinkle meat with salt and pepper, let stand for 15 minutes.
• Heat 2 TBS butter in a frying pan large enough to hold everything. Add sliced onion, cook over medium heat for 5 minutes.
• Add meat to pan and cook for 3 minutes, turning meat to brown evenly.
• Stir in flour and mustard, and cook 1 minute more. Add 1/2 cup wine and optional tomato paste. Reduce heat to low, cover pan and simmer for 5-10 minutes, stirring frequently.
• In another frying pan, heat 2 TBS butter. Add minced onion and mushrooms. Cook over medium heat 2 minutes. Add 2 TBS wine and cook 2 minutes more. Add mushroom mixture to meat mixture. Check seasonings and add warmed sour cream.
• Over lowest possible heat, simmer for 5 minutes to heat through. Do NOT let it boil.
• Serve over hot rice with a green vegetable on the side.
