– 4 tablespoons oil

Oil is a liquid fat extracted from plant or animal sources, characterized by its liquid state at room temperature and composed primarily of triglycerides. Common culinary oils derive from seeds (sunflower, safflower), nuts (peanut, walnut), legumes (soybean), fruits (olive, coconut), and grains (corn, sesame). Each oil possesses distinct flavor profiles, smoke points, and nutritional compositions depending on its origin and processing method—whether cold-pressed (unrefined, more flavorful, lower smoke point) or refined (neutral taste, higher smoke point, longer shelf life).

Oils vary significantly in their fatty acid composition, affecting both cooking suitability and health properties. Extra virgin olive oil, for instance, is minimally processed with a lower smoke point suited to finishing dishes, while refined vegetable oils tolerate high-heat cooking. Specialty oils such as walnut, hazelnut, and sesame serve primarily as flavor enhancers in dressings and drizzles rather than cooking mediums.

Oils function as both a cooking medium and a flavor component across all culinary traditions. They are essential for sautéing, stir-frying, deep-frying, and roasting, with the choice of oil depending on the desired smoke point and flavor contribution. In dressings, marinades, and finishing applications, oils provide texture, carry fat-soluble flavors, and contribute richness to dishes. Cold-pressed and specialty oils (olive, walnut, sesame) are often reserved for drizzling, emulsifying, or seasoning to preserve their distinctive characteristics, while neutral refined oils (vegetable, canola, grapeseed) serve as workhorses in professional and home kitchens where cooking temperature and ingredient flavor neutrality are priorities.
