Add enough oil to a saucepan to cover the bottom
Warm it on a medium heat on the hob
Once the oil is heated add enough popcorn to the oil to just cover the bottom of the pan and then put the lid on.
Listen and watch if you have a glass lid for the popping to start.
Move the pot over and back on the heat till the popping begins to slow down.
Turn off the heat but keep your pot on that ring and continue the shaking and listening for the popping till it is all but finished.
Lift the lid and season your popcorn to taste
