So judging by what I've read of this thread, I'm in the minority (possibly of one!) that feels that no-one so far has delivered on the brief. Terribly boring, most of it. I feel they should just give Heston a call and have done with it.
Yes, so far this series I just keep thinking Heston would wipe the floor with all of them, You just know his interpretations of the brief would be outstanding!
But unfortunately these guys only have a limited time to cook and prepare their dishes something Heston doesn't have to worry about on his show!
I'm sure if you give some of the chefs an entire day of preparation (and a highly skilled team of assistants) then they could easily compete with anything Heston could offer.
