Must have a look at pinch of nom - that recipe sounds yum! 24 sounds like a good number to do, lubilu. I've not been to a taster yet - just the way it's worked out with the groups I've been able to go to.
Funny that you say you can't see the difference, trills, as I came on here today to say I've done photos the whole way through so far (never done this on previous weight loss attempts and regretted it) and am miffed that I can't see a difference yet, either! In my case I think it's because I've a long way to go, so although I've lost nearly 1.5 stone it's not a visible difference yet. I think it's also not as easy to see the difference in yourself as someone else could, if that makes sense. Nice of your leader though and I bet there is a difference!! :)
