Most cooking oils don’t actually “boil” in the way water does—they smoke first. Water boils at 212°F (100°C), but oils hit their smoking point way before they ever bubble.
For example, olive oil starts to smoke around 375-400°F, while avocado oil can handle a blazing 520°F. So the real question is: What temperature does oil start throwing a tantrum? That’s the smoke point, and it’s your kitchen’s best friend.
