That ain’t no brisket. Looks more like ribs. Never saw a brisket with bones in it.
There are no bones in that photo, just weird light bouncing off the unsauced spots on the rather smooth top surface of the brisket slices, which are cut across the grain. Obviously not ribs, I know ribs.
The brisket does look really dry. Maybe it is a guava paste based sauce rather than tomato.
