Make the dough by adding the flour, yeast, salt, and sugar. Mix.
Add the water, and with your wooden spoons, or hands, mix until blended.
Cover the bowl with a towel, and let it sit at room temperature until the dough has doubled in volume, about 2 hours.
Once risen, divide into three portions.
Preheat your oven to 475 degrees, and place your cast iron skillet in the oven to preheat.
Once the oven is preheated, use kitchen mits to remove the extremely hot cast iron skillet from the oven.
Toss in the butter, and give that a swirl.
Add the portion of rolled out dough and place on the bottom of the cast iron skillet.
Add the pizza sauce and barbecue sauce on top of the dough, and mix that with a spoon, covering the majority of the dough.
Top with most of the shredded cheese, leaving a bit for the topping.
Add the chopped rib meat, then top with the thinly sliced onions and jalapeño peppers.
Top with any remaining mozzarella cheese.
Use your kitchen mits, and place the cast iron skillet back into the oven, and cook for about 25 minutes.
Once browned and the cheese is nice and melted, remove the pizza from the oven.
Drizzle with a bit more of the barbecue sauce.
Let the pizza rest for about 10 minutes, then carefully lift it out onto a pizza board, or cutting board before serving.
Slice into wedges and enjoy.
