I think that they had hoped the variety would be fun and surprising;
That's exactly what I'm finding so far. I just received my copy yesterday and in flipping through it I come across so many items that I just wasn't thinking of at that moment. Then I run off on another tangent and am amazed at where I ended up from the original search.
One thing I find though is the pointing out of what to avoid makes me want to try those combinations to see for myself! (the contrarian in me I suppose...)
Well, as was pointed out further upthread, some things are considered very differently by some of the chefs consulted in the book, highlighting the fascinating fact that we experience taste VERY differently! Yeah, trying combinations that it says to avoid could be interesting (in a good way, even). Some of the recommended combinations sound unlikely to me, but yeah, I'll probably try at least some of them out of curiosity. Good fun, anyway!
