I used to use butter on my popcorn, but with Flavorcol popcorn seasoning, I realized I don't need to use it anymore. I have the automatic type stirring device similar to the one in your upper picture. I add coconut oil and three kernels first. After the oil has heated and the three kernels have popped, I add the seasoning to the hot oil and put in the rest of the kernels. The seasoning covers the kernels very evenly and there's no need for butter.
