Make sure to buy popcorn kernels and not normal corn kernels.Take a wide thick bottomed pan with lid, I used my pressure pan.Add oil to it.
Swirl the pan so that oil is evenly distributed. Heat oil in medium flame,then add 2 corn kernels it will pop up in few seconds.This is the right temperature we need.Now measure popcorn kernels.
Add it,give a quick stir and cover it with a lid.Simmer the flame.Now lift the pan from flame and shake it for 2 seconds then place in flame.
Repeat this until all the kernels are popped out.Once the popping sound is stopped, you can switch off flame and remove it.Set aside.
Take butter in a tadka pan, heat it up for just 2-3 seconds until it melts.Now pour it over the popcorn.Add salt and toss it.
