Damn Diggity. It’s also el Cuycuy season at Marshall too, I need to drop by and see those dudes soon.

In my experience, Typically a pink-ish sauce consisting of Mayo, ketchup and other stuff. Mine had Worcestershire sauce, pickle relish, mustard powder and, garlic powder in it.

Heard, chef

This is true.

From what I understand, with a White Castle burger your goal is to more steam the burger with the onions with a preflattened patty. In this, you smash the onions into the burger searing everything together.

Ultimately, ground beef and cooked yellow onions are great together.

I suppose so

Tbf, Im an Oklahoman and didn’t know they were an Oklahoma thing until recently, I’ve been making these for years. I just thought it was a good way to make a burger.

Thinly slice onions, make two 2-3oz balls of ground beef, have seasoning and cheese nearby.

Drop onions on griddle into two piles, season, flatten a patty into each pile the onions, like making the onions become part of the patty, cook until crispy, season patty, flip, put American cheese on each patty, stack then serve on a toasted bun. I made a burger sauce with Mayo, ketchup, garlic powder, w-sauce, and sweet pickle relish.
