Ok, so I am planning to do 5 pork butts in my smoker for my kids birthday party. I am wondering how much sauce everyone thinks I will need. I am planning on around 25 people. Maybe a few more, but no more then 30. Some of them will be kids or older grand parents. I am leaving the BBQ sauce off and everyone can put their own on the sandwiches. I have already made 4 cups of Mustard sauce to start. Wondering if i should do 4 or 6 cups of a traditional KC style sauce? Or is that enough? I have never done an event this size where I made the food all by myself.
