Sicilian Clam & Mushroom Soup

Why I Love This Recipe
This is my adaptation of a delicious soup offered at a small Italian restaurant in Bradford, VT.
Ingredients You'll Need
1/2 Tbl. Margarine or Butter.
2 Tbl. chopped Onion
1 Cup (or more) sliced canned or fresh Mushrooms
2 Tbl. Flour
1/4 Tsp. Pepper
2 Tbl. Sherry or Marsala
1/2 Tsp. Worcestershire
2 Cups Chicken Broth (or Boullion)
1 6 oz. Can minced Clams, and their broth
2 Cups Half & Half
Optional: Chopped Chives and Parsley.
Directions
In a soup pot, melt butter.
Add onions mushrooms and pepper; cooking till onions are translucent.
Sprinkle flour over all then stir and cook for a minute.
Deglaze with the Marsala, then immediately add the chicken stock & Worcestershire, stirring until it comes to a boil and is slightly thickened.
Allow to simmer for a couple of minutes, then add the clams and their broth, and the half & half.
Bring soup back to almost boiling before serving.
NOTE: As with any dairy-based soup, do not allow to boil, or it will separate.
This soup tastes even better if made the day before serving, to allow flavors to develop.
