I still never figured out why White Castle hamburger patties have holes in them and Kyrstal burgers don’t. They’re about the same size.

To make sure you get an onion in every bite.

To allow steam to heat the onions nd top bun while they cook.

To allow even cooking for a fast food burger!

To cook them evenly and faster. That’s why White Castle did it. Same as the crackers. I was right. :-)

White Castle burgers aren’t grilled, they’re steamed. They stack a pile of onions on the grill,
then put 30 patties (exactly the number in a Crave Case!) on top. The steam travels through the
onions and cooks the burgers, while the holes in the burgers let the steam get inside and through
the patties. This ensures an even cooking surface across the patties and eliminates the need to
flip the burgers (remember, they are being steamed). It also means they need to spend less time
on the grill — and they can get out faster.

Kyrstal Burgers are grilled.... different cooking method.

It started out as a WW II meat saving development, and they stuck with it.
