PASTA AND BEAN SOUP (PASTA E FAGIOLI)

Steps:

• Combine beans and water in an 8-quart heavy pot and soak, covered, 12 hours.
• Add vegetables and 1 tablespoon rosemary to pot and simmer, covered, until beans are tender, about 2 hours.
• Using a slotted spoon, set aside 1 heaping cup bean mixture, then reserve 2 cups cooking liquid separately.
• Force remaining soup through a food mill into a very large bowl.
• Cook pancetta in cleaned pot over moderate heat, stirring, until it begins to render its fat.
• Add remaining rosemary and cook, stirring, 15 seconds.
• Stir in puréed soup, reserved whole beans, salt, and pepper and bring to a simmer, stirring frequently and scraping bottom with a wooden spatula to keep soup from sticking to pot (thin with some of reserved bean liquid if necessary).
• Add pasta and simmer, stirring frequently, until pasta is cooked, about 12 minutes.
• Serve soup drizzled with olive oil.
• -This soup is best the day after it's made.
• Cool it uncovered, before chilling, covered, up to 4 days.
• -You can use a blender or food processor instead of a food mill to purée the soup, but pulse briefly.
• This soup should be textured and thick.
• Makes 4 quarts, serving 8 to 10.
