Soup seasoning is an important part of making a delicious soup. THYME, MARJORAM, SALT, HERB, and BASIL are all common seasonings used to enhance the flavor of soups. THYME is a fragrant HERB with small leaves that has a slightly minty flavor. MARJORAM is a milder version of oregano with a sweet, woody flavor. SALT is a mineral that is used to bring out the flavors of other ingredients. HERB is a broad term for any plant with leaves, seeds, or flowers used for flavoring food. BASIL is an aromatic HERB with a sweet, peppery flavor. All of these seasonings can be used to make a flavorful soup.
