Crab and Shrimp Seafood Bisque

You can use uncooked medium Shrimp also. I just had two packages of the Salad Shrimps on hand and decided to use them.
Fresh mushrooms would have been better.
Unfortunately, I did not have any and was trying to pull a recipe from what I had on hand.

Ingredients :

3 tablespoons butter
2 tablespoons chopped green onion
2 tablespoons chopped celery
3 tablespoons all-purpose flour
2 1/2 cups milk
1/2 teaspoon freshly ground black pepper
1 tablespoon tomato paste
1 cup heavy whipping cream
8 ounces of crab meat
4 to 8 ounces small cooked shrimp or other seafood
2 tablespoon sherry wine*

 Preparation :

Melt the butter in a Dutch oven or large saucepan over medium-low heat; add the chopped green onion and celery. Saute, stirring, until tender.
Blend the flour into the butter and vegetables until well incorporated. Continue cooking, stirring, for about 2 minutes.
Warm the milk in another saucepan over medium heat.
Slowly stir in the warmed milk and continue cooking and stirring until thickened.
Add the freshly ground black pepper, tomato paste, and heavy cream.
If desired, puree the soup in a blender or food processor** at this point and then return it to the saucepan.
Stir in the crab, shrimp, and the sherry. Bring to a simmer.
Serve hot.
Tips and Variations
Feel free to add small cooked bay scallops or lobster instead of the shrimp.
Replace the green onions with finely chopped shallots.
If desired, garnish the soup with thinly sliced green onion tops, cilantro, or parsley. Or add a spoonful of sour cream and swirl it.
