I’ve watched a bunch of mukbang burp compilations and the one thing that seems to get people burping, much to my surprise, is a seafood boil! I am watching a video of someone trying a seafood boil (not burp related) and the person has burped 5 times in less than half an hour and it’s an edited video so those were intentionally left in, sometimes even cut to the burp. I have no idea what it is about a seafood boil that would make people burp.
Any other things you noticed? Anything in real life? I would say other burp-inducing foods I have observed are burgers and pizza. Also Thai.
