Beef Stroganoff

Directions

1. 1
   make a paste with dry mustard, 1 1/2t sugar, salt and water (just enough water to make a thick paste) set aside. Use less mustard for more mild sauce. This is 'tangy'!
2. 2
   Heat 1-2 T oil and saute the onions, mushrooms and garlic. Drain, set aside.
3. 3
   In 2 batches, cook the beef in the rest of the oil. I prefer the beef to be rare, so I just sear it -but cook longer,as you like.
4. 4
   Stir in the pepper and the mustard paste.
5. 5
   Add sour cream, stir well. Add more sour cream if you like more sauce (I do).
6. 6
   Add remaining sugar.
7. 7
   Cook over low heat 5-10 minutes.
8. 8
   Serve over egg noodles or rice.
