Manhattan Clam Chowder

Cook bacon in a 2- to 3-quart heavy saucepan over moderate heat, stirring, until golden, about 5 minutes. Reduce heat to moderately low, then add onion, bell pepper, and celery and cook, stirring, until softened, about 5 minutes. Stir in potato, bottled clam juice, and tomatoes (with juice) and simmer, covered, 10 minutes. Stir in clams and simmer, covered, stirring occasionally, until clams open wide, 8 to 10 minutes. (Discard any clams that after 10 minutes have not opened.)

Remove pan from heat.

Remove most of clamshells with tongs, then detach clams and return them to chowder. (Keep a few in their shells for garnish.) Stir in parsley and salt and pepper to taste.

Chowder, without clams or parsley, can be made 1 day ahead. Bring to a simmer before adding clams and proceeding.
