Are we looking at the same meatball because I don’t see any darker areas? I see some flecks of spice, but that looks like an unseared ball of meat to me. There are some tinges of red, but those are from the sauce poured over it, not from cooking. You can see the remnants of the sauce at the base of the meatball mixing with another completely different sauce. Pretty sure that meatball is just unseared boiled meat.
