We all know that homemade broth or stock is a thing of beauty and delight. There's an immense amount of flavor in even the weakest homemade broth, and in an ideal world we would continually replenish our quarts of chicken, beef, turkey, and vegetable broth in the freezer for impromptu soup-making. In reality, though, we never have enough homemade stock for every weeknight cooking project — especially during Soup Week! So, the question is, which storebought broth is best? Do you have a favorite? Any recommendations?
