Understanding Smoke Point and Stability The single most critical specification for any frying fat is its smoke point. Highly stable oils resist breaking down, which means they have a longer usable life and produce fewer harmful compounds.

Using a low-stability oil results in faster rancidity, off-flavors, and a higher likelihood of oil splatter in the pan. Unrefined, or "virgin," oils are extracted through mechanical pressing without chemicals or high heat.
While they offer appealing health benefits and distinct tastes, they have lower smoke points and are generally unsuitable for high-heat frying. This neutrality is particularly important when frying items like potatoes, chicken, or fish, where you want the natural ingredient to be the star of the dish.
