Crab Soup

I have been wanting to try to make that crab soup I had in Baltimore for a couple months now. I don't have a recipe, So I am winging it. Penny and I went to Costco today and they had the big King Crab legs, So I got enough for Crab Cakes and Crab Soup.
Ingredients

3/4 cup chopped green onion, with tops
2 teaspoons minced garlic
4 tablespoons (1/2 stick) butter
3 tablespoons all-purpose flour
2 cups fish broth
1 cup heavy cream
1 cup milk
1 pound crabmeat, picked free of shell
1/4 cup sherry
1 tsp lemon juice
1/2 tsp pepper
1/2 teaspoon salt
1/2 teaspoon white pepper
1/2 teaspoon garlic powder
1 cup freshly grated Parmesan
1/4 cup chopped fresh chives

Directions
Saute chopped green onion and garlic in butter until tender. Stir in flour, stirring until well blended. Slowly add 2 cups of the fish stock, continuing to cook until smooth and bubbly.

Slowly add cream and milk. Stir in crabmeat. Add sherry, lemon-pepper seasoning, salt and white pepper. Simmer until piping hot; adjust seasoning (sherry, salt, and pepper), to taste. Serve in bowls topped with cheese and chives.

This soup was so good. Second best to Baltimore. If I had Fresh Baltimore crab it would contend with their soup. The crab cakes were great too. I will definately be making this soup on a regular basis.
