I just saw a video, I don't understand.

This asian guy (no words just a video/shorts I think)

Guy took a slab of beef, not sure which cut, seared the outside , all 6 sides,
put it into a ice bath, took it out sliced it up into thin long rectangles.

made some kinda salad, made what looked to be a marinade coated everything and went to town on it.

Almost like a beef Sashimi ? if that is the right word.

Can you do that ? I mean I've heard of steak tartare, but why sear it ?

thanks !
