This was my mom's recipe that she handed down to me. I always loved her baked beans. This can easily be doubled or more for large crowds of people. Perfect for a potluck or cookout. You can also bake this in a crock pot to take with you. Just bake for about 4-6 hours in crock pot instead of in oven. For the mustard, I like Dijon, but I have also used yellow mustard or Gulden's spicy mustard.
