He suffers from the same problem as a lot of TV chefs doing their travelling bit. He's showing us his holiday snaps and doing the odd bit of cooking where he tries his hand at "improving" the way the locals cook but manages to miss the point.
The whole thing was mostly okay viewing if you can ignore him saving "bruv" every time he talks to someone. That said, he's not really doing much more than treading the well worn trail and "uncovering" food that everyone knows is there anyway (I'm guessing we've got a soul food episode coming up?). Missed opportunity when there's so much more to see.
That said, him sympathising at the "brutal death" of the gang-leader in the last episode was a bit in poor taste. It's not nice for his family but really, being a leader in the bloods he's likely to have taken or ordered the taking of enough lives himself.
