OMG... I have never had braunschwieger without mayo. I just came back from the market with some and thought the same thing... what IS the difference between liverwurst and braunschweiger? My dad always ate braunshweiger (and called it liverwurst) on white bread with mayo. Mmmmm. I just checked out the Farmer John website to see what the difference is and it's minimal but notable. Basically liverwurst has some different spices. But it also has corn syrup and PORK SNOUTS! Both have pork, both have pork liver, both have bacon but liverwurst has PORK SNOUTS! I shouldn't have read it.
