Using a spice grinder or a mortar and pestle, grind the sea salt to a fine powder. Then measure out ½ teaspoons of the powdery salt.
Melt ghee in the microwave.
Stir salt and ranch powder together to mix evenly.
Heat 1 Tbsps ghee in a large saucepan (with a lid for later) over medium high heat. Put 3 popcorn kernels in the pan. When the ghee is hot enough for them to pop take them out and pour in all the kernels.
Cover the pan with the lid and gently shake the pan over the hot burner until there is about 3 seconds between kernels popping.
Remove from heat and pour popped corn into a large bowl.
Pour the remaining melted ghee over popped corn and toss to coat. Sieve half the flavour mixture over the popcorn and then toss. Sieve remaining flavour mixture over and stir again till evenly mixed.
Serve immediately or store in an airtight container. It will couple a few days without getting soggy.
