Smoke Point Isn’t Everything: How to Choose the Best Cooking Oil for High Heat If you've ever searched for the best cooking oil for high heat, you've probably seen the same advice repeated again and again: Choose the oil with the highest smoke point. It sounds logical. A pan gets hot, oil starts smoking at a certain temperature, so the oil that smokes at the highest temperature must be the best choice. The problem is that food science is not quite that simple. Smoke point is useful information, but it tells us only part of the story. An oil's behaviour during cooking also depends on its fatty-acid composition, antioxidant content, level of refining, freshness, temperature, cooking time and whether it has already been heated before. That is particularly important during frying, where oil can remain hot for much longer than it does during a quick sauté. So instead of ranking cooking oils by one number, this guide looks at what actually happens to oil under heat and how you ca...
Cold-Pressed vs. Refined Oils: What Actually Matters Short answer: Cold-pressed (unrefined) oils deliver bigger flavor and more of the plant’s natural compounds; refined (RBD) oils are cleaner-tasting, more heat-tolerant, and last longer. Use both—just match the oil to the job. Cold-pressed preserves flavor with minimal processing; refining removes odors/color and raises heat tolerance. The quick take (read this first) Cold-pressed / unrefined : vivid flavor; best for dressings, dips, finishing, and low–medium heat. Refined (RBD) : neutral taste, higher smoke points , longer shelf life; best for stir-fry, searing, and deep-frying. For everyday health, favor unsaturated oils (olive, avocado, canola, sesame, safflower/sunflower). Use saturated fats less often.
