First things first, make the popcorn! You can do this in a popcorn machine or make your own. To make your own: heat the oil in a heavy based saucepan with a well fitting lid until hot. Add popcorn kernels and place the lid on. Once you hear the kernels begin to pop, give the saucepan a shake to help stop them sticking to the base . As soon as the popcorn stops popping, or the popping becomes quiet, remove from the stove and pour into a large bowl, and set aside.
