Whats the perfect time for heating oil in a pan or pot?

Hi there,


I've been trying to get the right amount of time to heat sunflower oil.





I use a non stick skillet/pan and the flame is just enough to boil water.





How long do I heat the pan before I add the oil and how long do I heat the oil after its in the pan before adding more cooking ingredients (eg. veggies, meat?)Whats the perfect time for heating oil in a pan or pot?
Typically you shouldn't heat Non stick (Teflon) more than 15-20 seconds due to potential toxins that are released from the dry Teflon - then add oil and let heat 25-35 seconds since Teflon is thinner and you are only using a small amount (~1tablespoon to fry veggies) It will heat very quickly. I would recommend that you get a cast iron or stainless steel pot when the Teflon begins to break down - they are much safe to cook with and easier to clean plus they last lots longer. Good Luck!Whats the perfect time for heating oil in a pan or pot?
The perfect time to heat oil would be right before you want to cook something in it.
You add the oil before you turn on the flame. And put it on med-high. The way you are doing it is why you get a singed taste.
