If you're interested in how fermentation is done by the experts, this is your book. If you are looking for recipes to try yourself, it's less useful. I've tried fermented pickles, wine and cider, vinegar, hot pepper sauce and several other things, so I'm a pretty adventurous. But I didn't find a single recipe that I thought might be interesting. This is the kind of interesting food you go out and pay Noma to cook for you.
