+ 1 tsp oil
Oil is calorie-dense (approximately 120 calories per teaspoon) and composed primarily of fat, including beneficial monounsaturated and polyunsaturated fats depending on the source. Oils vary in their fatty acid profiles and antioxidant content, with extra virgin olive oil and walnut oil notably rich in polyphenols.
About
Oil is a lipid substance derived from plant seeds, nuts, fruits, or refined from animal sources, characterized by its liquid state at room temperature and hydrophobic properties. Common culinary oils include those pressed from olives, seeds (sunflower, safflower, canola, sesame), nuts (peanut, walnut, almond), and coconut. Oils vary significantly in their fatty acid composition, smoke points, flavor profiles, and nutritional characteristics. Some oils, such as extra virgin olive oil, are mechanically pressed and minimally processed, while others undergo extraction and refinement processes to achieve neutral flavors and higher smoke points suited for high-heat cooking.
Culinary Uses
Oil serves as a fundamental cooking medium across virtually all cuisines, used for sautéing, frying, roasting, and baking. Different oils are selected based on their smoke points, flavor intensity, and nutritional profiles—extra virgin olive oil for finishing dishes and low-heat cooking, neutral refined oils (canola, vegetable) for high-heat applications, and specialty oils (sesame, walnut) as flavor enhancers in dressings and garnishes. Oils also function as emulsifiers in vinaigrettes, marinades, and mayonnaise, and provide textural richness to baked goods and sauces.
