Herb-infused oils are oils that have been combined with various herbs to extract their flavors and beneficial properties. Common oils used for infusion include olive oil, sunflower oil, and grapeseed oil. The process typically involves heating the oil gently with fresh or dried herbs, allowing the oil to absorb the herbs' essential oils and aromas. These infused oils can be used in cooking, salad dressings, or as finishing oils to enhance the flavor of dishes. Popular herbs for infusion include basil, rosemary, and thyme. Additionally, herb-infused oils can also be used in homemade beauty products for their nourishing qualities.
