Measurements
Which Cooking Oil Should I Use?
Compare suitable oils for sautéing, roasting, frying, and high-heat cooking using smoke-point guidance.
Refined avocado oil or Refined peanut oil or Sunflower oil
For saute around 400°F, the calculator keeps a practical margin below the listed smoke point.
- •Refined avocado oil: approximate smoke point 500°F.
- •Refined peanut oil: approximate smoke point 450°F.
- •Sunflower oil: approximate smoke point 450°F.
- •Smoke points vary with refinement, age, and impurities; discard oil that smells rancid or smokes persistently.
Methodology
How we calculate this
Oils are filtered by whether their approximate smoke point leaves a practical margin above the selected cooking temperature and matches the flavor preference.
The math
- Eligible oil smoke point ≥ cooking temperature + safety margin
- Current margin: 25°F for deep frying; 10°F for other methods
Worked example
At 425°F, an oil listed around 450°F retains a 25°F margin and can qualify for high-heat use.
Frequently asked questions
Helpful answers
Should I cook right at an oil's smoke point?
No. Choose an oil with a smoke point comfortably above the intended cooking temperature because refinement, age, and impurities cause variation.
Is extra-virgin olive oil suitable for sautéing?
Yes for many moderate-temperature applications. For very high heat or prolonged frying, a refined high-smoke-point oil offers a larger margin.
Can I reuse deep-frying oil?
Sometimes, if it was not overheated and is strained and stored properly. Discard oil that is dark, sticky, rancid-smelling, foamy, or smokes unusually early.
