That’s what I read. mostly bullshit from my experience as one… as an american, not as a peanut butter burger. Sounds like food from the great depression.
I ordered it once from my local burger place. Never again!
A quick google says it’s from Missouri, or Misery if you’re made to eat peanut butter on burgers.
(not that we believe everything on google)
I once mistakenly ordered the KFC burger with peanut butter.
Apparently they are band from feeding that to POW’s under the Geneva convention, if not, then they should be.
Stop talking about them as if they are fine dining. They are a step above maccy Ds at best.
The Elvis Burger from Oldies behind Q Square is really good.
What goes into an “Elvis Burger”?
I’m concerned it “ain’t nothing but a hounddog.”

It’s based on a sandwich he regularly traveled to Las Vegas for, with peanut butter jelly and bacon. They don’t overdo it, it all melts into a tasty sauce on the burger.
Hmmm. I wonder how drunk I’d need to be for that to sound like a good idea. 
Guy
I probably was, but it’s good!
Ok friends. I went down the rabbit hole researching peanut butter on burgers. I’d never heard of or even seen peanut butter on a burger before I came to Taiwan, so I figured it was just another creepy Taiwanese localization thing to fuck up a burger. You know, like how Taiwan pizza hut puts the most disgusting shit on dough and calls it pizza!
At any rate, I found out that it is an American thing. Albeit, a southern US thing and nothing I’ve ever seen or experienced in the pacific northwest of the US as I’m an flag waving yankee. I now understand @bz clever Elvis comment. Nice one!
So, without further eloquence and before I break my arm patting myself on the back for finding this information, here’s the straight poop from Gemini.
I disrespectfully disagree. For me, no burger is “fine dining”. However, In-N-Out are way above anything that McD’s puts out. McD’s is low grade dog food. "There’s still marks where the jockey was hittin’ it!
Anybody remember Fudruckers? A side of beef hanging in the glassed in refrigerated room where they would grind the burgers fresh! They also baked their own buns on site. There are still a few left.
Maybe you should do some more research mate.
A burger is made up of ground up beef, preferably not too lean. The best (and the original) ones imo are smash burgers. That’s ground beef squashed on a pan.
Like this.
This is nothing you cannot do FRESH in Taiwan, or anywhere else that has beef. I respect In and out if they don’t want to do business outside of the USA but the reasoning/excuse is weak. And on top of that their pop up business model just totally obnoxious.
As a Missourian, I never heard of peanut butter on hamburgers until I came to Taiwan either. I wish Taiwan could get some Culver’s.
It’s strictly to protect their IP so if some enterprising lao-wai puts up a burger shack with their sign they can sue in Taiwanese court.
I really wonder just how many countries they do this in…
Wait are you saying that if In-and-Out did NOT do this kind of (evidently expensive) pop up, that an enterprising lao wai COULD put up a burger shack with their sign? i.e. that there is no IP protection without first having a pop up?
Guy
It makes it easier to defend, it shows they have an active interest in protecting the IP in Taiwan. Also the publicity around the stunt makes people aware of brand ownership, they are in it for the clout.
Maybe I’ll try a fast food peanut butter burger and then if I like it a homemade one might in order.
Well its not 100% strictly to protect IP its also about the PR. PR for a brand that will never be here, nor anywhere other than the US. And as you can see from all the gimps lining up and reporting on the story, the PR works.
They have a peanut butter burger at Lazy Dog Burgers in Hualien. I haven’t tried that one, but I love their smashed burgers and chicken sandwiches there.

Mosburger have had a peanut butter breakfast burger for years. It’s ok.
