Herb-infused oils are oils that have been combined with various herbs to extract their flavors and beneficial properties. Common oils used include olive oil, canola oil, and grapeseed oil. The infusion process typically involves heating the oil gently with fresh or dried herbs, allowing the oil to absorb the herbs' essence over time. These oils can enhance the taste of dishes, making them popular in cooking and salad dressings. Additionally, herb-infused oils may offer health benefits, as many herbs contain antioxidants and anti-inflammatory properties. Popular herbs for infusion include basil, rosemary, and thyme.
