Peanut oil is extracted from peanuts, either by pressing raw or roasted peanuts or via chemical extraction. It is a vegetable oil commonly used in frying, sautéing, and baking. Its light flavor makes it ideal for dishes where you don’t want the oil to overpower the natural taste of food.
Peanut oil is popular in Asian cuisines, especially Chinese and Indian cooking, due to its ability to handle high cooking temperatures without breaking down. It’s also appreciated for its nutritional content, as it contains essential fatty acids and antioxidants.
There are different types of peanut oil:

- Cold-Pressed Peanut Oil – Extracted without heat, retains most nutrients and flavor, suitable for salad dressings.
