peanut or veg oil

Peanut oil is a vegetable oil extracted from the seeds of the peanut plant (Arachis hypogaea), native to South America and now widely cultivated in tropical and subtropical regions, particularly in China, India, and the United States. The oil is pale yellow to clear in color with a mild, slightly nutty flavor when refined, or a more pronounced peanut aroma when unrefined (cold-pressed). Refined peanut oil undergoes processing to remove flavor compounds and impurities, resulting in a neutral-tasting, high-smoke-point oil suitable for high-heat cooking.

Vegetable oil is a broad classification referring to oils extracted from plant sources, most commonly soybean, canola, sunflower, safflower, or a blend thereof. These oils are typically refined through mechanical pressing or solvent extraction, then refined, bleached, and deodorized to create neutral-flavored, versatile cooking oils with relatively high smoke points.

Peanut oil is prized in Asian cuisines, particularly Chinese and Southeast Asian cooking, for its high smoke point (around 450°F/230°C for refined oil), making it ideal for stir-frying, deep-frying, and wok cooking. It imparts subtle flavor to finished dishes while withstanding intense heat. Unrefined peanut oil, with lower smoke point and stronger flavor, is used in dressings and finishing applications.

Vegetable oil serves as a neutral all-purpose cooking medium across global cuisines. Its mild flavor and reliable smoke point (typically 400-450°F/200-230°C depending on type) make it suitable for frying, baking, roasting, and salad dressings where ingredient flavors should remain unmasked. It functions as a fat base in mayonnaise, margarine, and other processed foods.
