It's such fun making your own popcorn @livinguktaiwan! You do it on the stovepot in a deep heavy-based pot, just about 3 tablespoons of oil in the base, a single layer of popcorn kernels, lid on and wait for the magic. It always amazes me how those small kernels fill the pot. My sons often used to put too much in the pot, and that's when the fun starts and things get out of hand as the volume and the popping starts lifting the lid😅
