For rave-worthy soups, skip the store-bought stock. You can extract a cleaner, stronger broth from a combination of water and several pantry ingredients. It's all about layering powerful flavor-enhancers that you probably already have on hand - bacon, tomato paste, herbs, peppercorns, a Parm rind, and, of course, kosher salt.

When making any pureed soup, don't blend all the liquids and solids together at once. Hold back some liquid at first and use it to thin the soup as needed. You can always add more liquid, but there's not much you can do to fix a too-thin soup.

Simmering vegetables in a covered pot over low heat so that they steam in their own liquid - a French technique called a l'etouffee - is the ticket to achieving a soup with pronounced depth.
