Excellent technical content - I learnt a ton of things, which actually make a difference in how I approach some of my cooking, on all topics of the book.
But the tone can be grating at times - I'm absolutely fine with the nerd refs, but some of the remarks kind of read as "wives, amirite? :wink wink nudge nudge", which gets old very fast.
I could also have done with a systematic conversion to Celsius for temperatures, but at least there's a easy-to-refer table at the end of the book on the inner cover :)
