Oil is a lipid extracted from plant seeds, nuts, fruits, or animal sources, characterized by high fat content and liquid state at room temperature. Common culinary oils include olive oil (from olive fruit), canola oil (from rapeseed), sunflower oil (from sunflower seeds), and coconut oil (from coconut meat). Each oil possesses distinct flavor profiles, smoke points, and nutritional compositions that determine its suitability for various cooking methods. Olive oil ranges from delicate and fruity (extra virgin) to neutral and refined; seed and nut oils vary from mild to pronounced in flavor depending on pressing and refinement methods.

Oils are composed primarily of triglycerides—fatty acids bound to glycerol—with varying proportions of saturated, monounsaturated, and polyunsaturated fats. Extra virgin and cold-pressed oils retain natural compounds including polyphenols, chlorophyll, and vitamins, while refined oils undergo processing that removes flavor compounds and extends shelf stability.

Oil serves as a fundamental cooking medium across all culinary traditions, facilitating heat transfer for sautéing, frying, and roasting. It functions as an emulsifier and flavor carrier in dressings, vinaigrettes, and sauces. Different oils are selected based on smoke point—refined oils with higher smoke points (peanut, canola, avocado) suit high-heat cooking, while delicate oils (extra virgin olive, walnut, flaxseed) are reserved for finishing dishes, drizzling, and cold preparations. Oils also provide textural richness in baking and contribute to the preservation of foods through confit and pickle preparations.

Regional preferences shape oil selection: Mediterranean cuisines emphasize olive oil, Asian cuisines favor sesame and peanut oils, and Northern European traditions traditionally use animal fats. Flavored and infused oils—garlic, chili, herb-infused—add complexity to simple preparations.
