***Note: If the soup is not thickening to your desired consistency, (it should due to the flour) you can add just a TINY bit of cornstarch slurry. (Mix of a little cornstarch and cold water, whisked in a small bowl) Stir in and bring to a quick boil, it should thicken immediately but wait because it may not be needed but if so just a little bit so it remains a chowder and doesn't turn into a gravy.
