Melt butter in a small bowl. Mix in garlic salt, dressing, hot sauce (Franks is recommended) and cayenne. Add more Cayenne if you like it a bit spicier or omit it for a mild taste.

In a heavy pan with a lid melt coconut oil and add popcorn. cover the lid and cook over medium high heat occasionally shaking the pan. when the popping slows to one pop every few seconds take the pan off the heat.

Allow the pan to rest for 2 minutes then uncover the pan and push the popped corn to the sides leaving a "well" in the center. Spoon butter and seasonings into the center and mix the corn well into the melted butter. Work quickly, if the corn sits in the liquid too long it will be soggy and the flavor will be uneven. By working in the hot pan you also ensure the butter is fluid enough to evenly coat the corn.
