Ray Mears - Legend or Fraud?

I've just seen some of Ray Mears on TV, chatting about how the forests of Britain can sustain anyone indefinitely. Pretty cool, I thought, as Ray goes on to explain the characteristics of the most common edible mushrooms. He says "oh, those will be excellent", and the scene cuts to Ray sitting in a clearing with a fire going and the mushrooms nicely sliced. Hang on...a fire? How did he do that? Never mind, I'm sure it's possible by rubbing sticks together or something. And I'm sure he sliced the mushrooms with a sharp rock.
Then things get a bit less realistic. He whips out a wok and fries the mushrooms with butter and tomatoes. Come on Ray, did you fashion that pan from twigs and berries? Did you breed cattle and churn the milk into butter? But in the end I excuse him the discrepancy and put it down to convenience.
But then, inexplicably, he quips "much better with a dressing and bread" and magically materialises some ciabatta bread and balsamic vinegar. Come on Ray, there's ease of filming and then there's just cheating mate. We could all live in the forest indefinitely if Domino's know which tree to deliver your fucking pizza to.
In a different scene, he explains the nutritional virtues of chequer berries, or something like that. "Lovely, I could eat them all day, but they've been forgotten by rural society" he gleefully states. It's only at the last second when he quickly mutters the probable reason for their banishment from the menu- "best not to eat the stones in them though, they contain cyanide".
Oh, and right now, he's glazing a pig on a spit with a brush he made from a branch. You tell me-genius or cheat?
