– 3 tbsp cooking oil
Cooking oils are calorie-dense (approximately 120 calories per tablespoon) and composed entirely of fat, providing essential fatty acids such as linoleic and alpha-linolenic acid, depending on the oil type. The nutritional profile varies significantly by source: olive oil is rich in monounsaturated fats and polyphenols, while vegetable and canola oils contain higher levels of polyunsaturated fats.
About
Cooking oil refers to any liquid fat derived from plant, seed, or occasionally animal sources that remains liquid at room temperature. Common culinary oils include canola, vegetable, olive, sunflower, safflower, peanut, and sesame oils, each with distinct origins, processing methods, and smoke points. Plant-based cooking oils are composed primarily of triglycerides and varying ratios of saturated, monounsaturated, and polyunsaturated fatty acids, which influence their stability when heated and their flavor characteristics. Refined oils are processed to remove impurities and odors, while unrefined (virgin or cold-pressed) oils retain more of their original flavor and nutritional compounds but have lower smoke points.
Culinary Uses
Cooking oils serve as the primary fat medium for sautéing, frying, roasting, and baking across all culinary traditions. They are selected based on intended cooking temperature: high-smoke-point oils (canola, vegetable, peanut) are used for high-heat applications such as stir-frying and deep frying, while lower-smoke-point oils (extra virgin olive, walnut, sesame) are typically used for finishing dishes, salad dressings, and lower-heat cooking. Oils also function as flavor carriers and contribute to texture in baked goods, emulsified sauces, and dressings.
