The top is better equipped to absorb all those delicious, mouthwatering burger juices, so by flipping your burger over, you protect the top bun and keep it crisp.
Simon Dukes, the founder of Burger Lad, told Insider, "The crown will then hold the weight of everything else, and there is less likelihood of it falling apart in your hands."
This technique ensures every bite is infused with the rich flavor of your patty and toppings. He added, "A true burger connoisseur should always eat their burgers upside-down."
Depending on the size of your burger, you can flip it as soon as your plate arrives to avoid letting any sauces soak into the bun or flip it as you bring it to your mouth.
