Herb-infused oil is a culinary oil that has been infused with the flavors and aromas of various herbs. Common herbs used include basil, rosemary, and thyme. The infusion process typically involves gently heating the oil with the herbs, allowing the oil to absorb their essential oils and flavors. This creates a versatile ingredient that can enhance the taste of dishes, dressings, and marinades. These oils can be made at home or purchased from stores. They are often used in cooking, drizzling over salads, or as a dip for bread. Herb-infused oils not only add flavor but can also provide some health benefits associated with the herbs used.
