At least Mel and Sue tried to comfort the upset bakers or help hold things and calm them down and so on, as well as presenting, so there was a reason for them there. And they could do innuendo without it sounding sleazy, just kind of funny. Apparently they always tried to stop the cameras showing contestants who were really upset, too.
Noel and Matt are just childish and it's all about them, not about the contestants or the baking.
Yes Crystelle should have got a bit more recognition for her foccacia, even if it was annoyingly thin! I think she is putting on a slightly ditzy/anxious persona, but underneath is going to be a bit competitive in the end.
The milk bread task was odd though. I find all the tasks where they make other food out of bread or cake a bit strange, especially when it's flavoured with something completely different - like hog roast or courgettes made out of hazelnuts or condensed milk. And all the really bright colours, while impressive to look at, would be odd to eat!
And yes, much as I like Jurgen, what on earth was he thinking with kippers and eggs in focaccia?!
