You can get free clam chowder today at Shell Shack because it's National Clam Chowder Day! Shell Shack has seven locations in North Texas.
1 1/2 cups chopped onion
1 1/2 cups water
4 cups peeled and cubed potatoes
1 1/2 teaspoons salt
Ground black pepper to taste
3 cups half-and-half
3 tablespoons butter
2 (10 ounce) cans minced clams
Place chopped onion in large stock with some olive oil and cook 5 minutes. Stir in water and potatoes, and season with salt and pepper. Bring to a boil, and cook uncovered for 15 minutes, or until potatoes are fork tender.
Pour in half-and-half, and add butter. Drain clams, reserving clam liquid; stir clams and 1/2 of the clam liquid into the soup. Cook for about 5 minutes, or until heated through. Do not allow to boil.
