Clam Chowder-Market Street
(Serves 12)
Ingredients:
1 cup potatoes, diced ½ inch
1 cup celery, diced ½ inch
1 cup onion, diced ½ inch
1 cup green pepper, diced ½ inch
1 cup leeks, thoroughly washed and diced ½ inch
¾ cup chopped clams (canned or fresh)
¾ tablespoon coarse ground black pepper
1 ½ tablespoon salt
¾ tablespoon whole thyme
6 bay leaves
1 teaspoon Tabasco
¾ cup sherry wine (optional)
2 cups water
¾ cup clam juice (drained from canned clams or purchased separately in can)
¾ cup butter, melted
1 cup flour
2 quarts half-and-half

Combine melted butter and flour in oven-proof container and bake at 325 degrees for 30 minutes. In large saucepan, combine remaining ingredients except half-and-half. Simmer until potatoes are thoroughly cooked. Stir butter-flour mixture into chowder and stir until thick. Mixture will be slightly less thick than cookie dough. Remove chowder from heat. Stir in half-and-half until blended. Heat to serving temperature, stirring occasionally. Serve immediately.
