Cooking Oil
Description
Cooking oil is a plant, animal, or synthetic fat used in frying, baking, and other types of cooking. It is also used in food preparation and flavoring that doesn't involve heat, such as salad dressings and bread dips, and in this sense might be more accurately termed edible oil. Cooking oils are typically liquid at room temperature, although some oils that contain saturated fat, such as coconut oil, palm oil, and palm kernel oil, are solid.
There is a wide variety of cooking oils from plant sources such as olive oil, palm oil, soybean oil, canola oil (rapeseed oil), corn oil, peanut oil, and other vegetable oils, as well as animal-based oils like butter and lard. The choice of oil can be driven by health, flavor, or dietary requirements.
Common uses
Cooking oils are used for a multitude of culinary purposes, including frying, baking, grilling, and as a base for dressings and sauces. They are also used to sauté, stir-fry, and to add flavor and texture to dishes. Due to their high-fat content, they aid in heat transfer and can enhance the flavors of other ingredients.
