I was really surprised by the positive reaction on Twitter for my Jack Skellington Pizza, so I wanted to share how I made it. My apologies that I did not take photos of each step, but I hope the photos and descriptions provided will be helpful.
Step 1: Make your dough
You can use any pre-made dough or make your own. My favorite recipe is from King Arthur: http://www.kingarthurflour.com/recipes/the-easiest-pizza-youll-ever-make-recipe (I use the saf red instant yeast option). I made the dough a day ahead of time and put it in the refrigerator after letting it rise for about an hour and a half.
