Chapter: The Alchemy of Oils — Heat, Flavor, and Chemical Politics In the theater of the kitchen, oils are both actors and directors, invisible currents that shape taste, health, and culinary risk. Among the pantheon of liquid fats, six reign supreme: avocado, extra-virgin olive, canola, coconut, sunflower, and sesame . Each comes with its own history, chemistry, and theater of thermal limits—its smoke point—a crucible of chemical fidelity. 1. Avocado Oil: The High-Heat Strategist Avocado oil bifurcates into cold-pressed (unrefined) and refined . Cold-pressed oil is extracted mechanically [pressed or spun without heat or chemicals], untouched by chemical solvents [industrial chemicals used to maximize extraction]. Its subtle green tint and whisper of avocado aroma reveal the retention of vitamin E [antioxidant] and phytosterols [cholesterol-lowering plant compounds]. Its smoke point registers 375–410°F (190–210°C) —enough for sautéing and delicate dressings, but perilous a...
