Chef's flavorings are often made up of herbs, which are plants that have a strong aroma and flavor. Herbs are used to add flavor to dishes, and they can be used fresh, dried, or in a paste form. Common herbs used in chef's flavorings include basil, oregano, thyme, rosemary, sage, and parsley. These herbs can be combined with other ingredients such as garlic, onions, and peppers to create unique flavor combinations.
