Cooking Fats Guide
Smoke points, oils, butter, and storage — written plain, for everyday cooking.

Three things cooks get wrong about fats — and how to stop guessing.
Each fat breaks down at a different temperature. Know when to use which oil and why crossing the smoke point matters.
Finishing oils are not cooking oils. The difference is real, affects flavor, and a cheap neutral oil outperforms an expensive one in a hot pan.
Butter burns. Clarified butter does not. And oils stored in sunlight go rancid faster than most people realize.
Five focused guides. No padding, no filler.
What the number actually means, why it changes with each use, and a reference table for 12 common fats.
How to stop wasting expensive olive oil in a hot pan — and when drizzling it raw makes actual sense.
Regular, clarified, browned — three states of the same ingredient with very different uses and limits.
Light, heat, and air are all threats. A few storage rules extend the life of every fat in your kitchen.
You need three to four fats, not fifteen. Here is what to stock and why each earns its shelf space.
The smoke point where most common cooking oils start to fail — and produce acrid smoke and bitter flavor.
A recipe might say "heat oil in a pan" but never tell you how hot is too hot. Smoke points are the missing number. Once you know them, you stop scorching delicate fats and start using neutral ones where heat is the point.
Same ingredient, different outcomes depending on heat and timing.
Avocado oil, refined sunflower, and clarified butter all handle temperatures above 400°F without breaking down. Reserve them for searing, stir-frying, and anything that needs a very hot, dry surface.
Using extra-virgin olive oil here is the most common mistake. Its polyphenols — the compounds that make it taste good — are the same compounds that burn and turn bitter under high heat.
Smoke point guide
Finishing a sauce with whole butter, drizzling good oil over a finished dish, or using sesame oil to season — these are not cooking moves. The fat goes on after heat, and its flavor transfers directly into the food.
This is where spending more on oil pays off. You taste it. In a hot pan, you mostly do not.
Cooking vs finishing oilsA quick reference — match your cooking temperature to the right fat.
Softening vegetables, making scrambled eggs, sweating onions. Use whole butter or extra-virgin olive oil. Neither fat is stressed at this temperature.
Sautéing, shallow frying, pan sauces. Refined olive oil, coconut oil, and standard vegetable oil are all comfortable here. Whole butter starts to brown.
Searing meat, roasting vegetables, stir-frying. Use refined avocado oil, grapeseed oil, or clarified butter. Extra-virgin olive oil does not belong here.
Deep frying, smoking a cast iron, wok cooking. Refined avocado oil or refined peanut oil. At this temperature the wrong fat produces bitter compounds and visible smoke.
