White Castle is known the world over for its diminutive, and cheap, slider hamburgers. However, what if the burgers weren't designed to cost less than a buck? What if they cost over 400 times that? One food blogger has been looking into just that, creating a massively expensive White Castle burger out of fancypants ingredients.

Nick from Dude Foods, who is no stranger around these parts, has just unleashed one of his most ridiculous creations yet: the $400 White Castle slider. What makes it so expensive? He topped it with two expensive cheeses, Pleasant Ridge Reserve and Hook's 15 Year Cheddar, then ladled on $200 worth of Italian white truffles. He wasn't done, however. Finally, the slider received generous portions of duck foie gras, Russian caviar and a fried quail egg. Oh yeah. He also topped it with 24K gold flakes. It's not fancy unless it's gold.

If you have a whole lot of money to burn and the hankering to turn something lowbrow into something decidedly high brow, give his outlandish recipe a try. One thing to note, however: He said it tasted terrible.
