A little science behind why smash burgers taste the way they do.
Smashing the patty flat onto a screaming-hot griddle triggers the Maillard reaction — the same browning process behind seared steak and toasted bread — packing way more flavor into every bite.
A smash patty is thin enough to cook through in under two minutes flat. That speed is exactly what keeps it juicy instead of drying out.
We drop the cheese straight onto the hot patty the second it's smashed, so it melts into every crevice instead of just sitting on top.
