In medium-sized heavy-bottom saucepan, heat 2 tsp coconut oil over medium heat. Place 4 kernels in pan and cover. When kernels pop, pour in remaining kernels in an even layer. Cover pan, lift off the heat, and count to 30 seconds. Return pan to heat and, once popping is rapid, gently shake pan back and forth on burner with lid slightly ajar to release some steam. Once popping slows to several seconds between pops, remove pan from heat.
