Beginner Kitchen basics

Knowing when oil is hot, and smoke points is reading the signs that oil is hot enough to cook in, and choosing an oil that suits the heat.

How do you do it?

1. 

   1Heat the oil over medium to medium-high and watch the surface.

2. 

   2When it shimmers and flows thin like water, it's ready for sauteing.

3. 

   3If you see wisps of smoke, it's too hot; pull the pan off the heat for a moment.

4. 

   4For high heat, use oils with high smoke points like canola, peanut or avocado; save butter and extra-virgin olive oil for lower heat.

Why does it work?

Hot oil browns food quickly and keeps it from sticking. Past its smoke point, oil starts breaking down, tasting acrid and smoking up the kitchen; refined oils tolerate more heat than unrefined ones.

What are the common mistakes?

• Adding food to barely warm oil — it soaks up oil and turns greasy.
• Heating oil until it smokes heavily — off flavors, and it can catch fire.
• Searing in butter alone — the milk solids burn before the pan is hot enough.
