Shrimp Victoria

I received this recipe from Rhonda (yes the same Rhonda famous for her cakes). The recipe was included in a  memorial cookbook for her mother, Toots. I knew this was one of her favorites and have been meaning to try it forever. 
Well today was the day and now I regret not trying it earlier. It is quick, fairly easy and delicious!!! Next time I will add a little more cayenne pepper but other than that it was perfect!

• 1 pound raw shrimp (peeled)
• 1 cup sour cream
• 1/2 cup chopped onion
• 1/4 cup butter
• 1 tablespoon flour
• 1/4 teaspoon salt
• dash cayenne pepper
• 1 can mushrooms
• 1 1/2 cup rice or pasta

1. Saute the shrimp and onions in butter for 5 minutes, add mushrooms and cook additional 2-3 minutes.
2. Sprinkle flour, salt and cayenne pepper over shrimp. 
3. Stir in the sour cream and cook three minutes. Don't let it come to a boil.
4. Serve over prepared rice or pasta.
