The science behind smoke points

To comprehend how smoke points affect your cooking, it's important to understand the source and processing of different fats. Oils are typically extracted from nuts and seeds through mechanical crushing and pressing.

If the oil is bottled immediately, it retains its natural flavor and color, making it suitable for drizzling, dressings and lower temperature cooking.

Enhancing smoke points through refinement

To increase a fat's smoking point, manufacturers employ industrial-level refinement techniques, like bleaching, filtering and high-temperature heating. These processes eliminate compounds that are sensitive to heat, resulting in a neutral-flavored oil with a longer shelf life and a higher smoke point.

Similarly, clarified butter or ghee undergoes a process that removes heat-sensitive components like milk solids, raising its smoking point.

While cooking with smoking oil isn't always disastrous, it's important to note that heated fat past its smoking point can lead to negative consequences.

The breakdown of fat releases free radicals and acrolein, a chemical responsible for the acrid taste and smell of burnt food. Additionally, the closer a fat gets to its flash point, the more it produces ignitable gases, creating a potential hazard.

Benefits of using high smoke point oils

Choosing cooking fats with high smoking points opens up a world of culinary possibilities. Here are a few scenarios where high smoking point oils shine:

Searing: Achieve a perfect sear by using neutral fats like peanut, corn or vegetable oil. Heat the oil until it just starts smoking before adding your meat.

Sauteing: For sauteing, medium smoking point fats like virgin olive oil work well. Heat a small amount of oil until shimmering or lightly smoking, and add your ingredients, following the recipe directions.

Deep-frying: Opt for a high smoking point, neutral fat that can withstand the intended frying temperature. Using a thermometer will ensure precision. Be cautious with flavorful fats like beef tallow or schmaltz, as they can leave a waxy coating when cooled.

Stir-frying: Stir-frying demands a thin coating of smoking-hot oil to brown ingredients quickly while retaining their crunch. Choose oils like peanut or safflower with high smoking points for optimal and safe results.

To preserve the quality of your cooking oils, keep them away from light, heat, water and air, which can accelerate rancidity. Consider refrigerating oils like avocado, hazelnut, sesame and walnut to prolong their freshness.

Avoid storing oils over the stove, as the additional heat can expedite spoilage.
