New England Clam Chowder

Name: New England Clam Chowder
Ingredients: 3 strips thick-cut bacon (I used Neuske's, which I think is worth the extra cost); 4 tablespoons unsalted butter; 1 large onion (cut into 1/4-inch cubes); 1 rib celery (cut into 1/8-inch slices); 1 teaspoon chopped fresh thyme leaves; 2 bay leaves; 2 medium-size white potatoes (peeled and cut into ¼-inch cubes); 1/2 cup all-purpose flour; 3 cups bottled clam juice (divided); 1 pound chopped fresh clam meat (with juices (see Note)); Kosher salt to taste; 2 cups light cream; 1 teaspoon white pepper
