Oils & FatsYear-round. Most culinary oils are extracted from seeds, nuts, and fruits harvested seasonally but processed and stored for year-round availability. Specialty oils may have limited harvest seasons (e.g., extra virgin olive oil from October-February in the Northern Hemisphere), but refined versions remain consistently available.

Oils are calorie-dense (approximately 120 calories per tablespoon) and composed primarily of fats; composition varies by source, with olive and avocado oils rich in monounsaturated fats, while coconut oil contains high saturated fats. Most oils provide fat-soluble vitamins (A, D, E, K) and some contain polyphenols and other bioactive compounds.

About

Oil is a lipid extracted from plant seeds, nuts, fruits, or animal sources that remains liquid at room temperature. Common culinary oils include olive oil (pressed from olives, Olea europaea), vegetable/canola oil (refined from rapeseed), coconut oil (from coconut meat), and seed oils such as sesame, sunflower, and grapeseed. Oils vary significantly in flavor, smoke point (the temperature at which they break down), and fatty acid composition. Virgin and extra virgin oils are minimally processed and retain more flavor and nutrients, while refined oils are neutral-tasting and suited for high-heat cooking.

The term "oil" encompasses diverse products with distinct characteristics: some are prized for their robust flavor and aromatic qualities, while others serve as neutral cooking mediums. Smoke points range from approximately 160°C (320°F) for unrefined flaxseed oil to over 230°C (450°F) for refined avocado oil, making choice of oil crucial for different cooking methods.

Culinary Uses

Oils function as fundamental cooking mediums across virtually all culinary traditions. They are used for sautéing, frying, roasting, and braising; emulsifying dressings and sauces; finishing dishes; and preserving ingredients. Extra virgin olive oil is typically used unheated in Mediterranean cuisine for dressings and drizzling, while neutral refined oils serve high-temperature cooking. Specialized oils like sesame and walnut provide distinctive flavors as finishing touches or in Asian cuisines. The choice of oil significantly impacts the final dish's flavor profile and nutritional composition.

Forms & Preparations

Extra virgin — Cold-pressed, unrefined oil with minimal processing; retains robust flavor, aroma, and nutrients; low smoke point (~160°C/320°F). Used for finishing, dressings, and unheated applications.
Virgin (pure) — Lightly refined or mechanically pressed oil with moderate flavor retention; medium smoke point. Suitable for low-to-medium heat cooking and dressings.
Refined — Heavily processed oil with neutral flavor, extended shelf life, and high smoke point (190-230°C/375-450°F). Ideal for high-heat cooking, frying, and applications where flavor should not dominate.
Infused — Oil steeped with herbs, spices, garlic, or chiles to impart additional flavor. Used for finishing, dressings, and aromatic garnishing.
Spray — Oil dispensed as an aerosol mist, typically with lecithin or other emulsifiers. Used for light coating of pans and ingredients with minimal oil volume.
