Gadgets? Not exactly. In making our books, we had the opportunity to work with many different kinds of equipment. All of that experience has left us with some favorite kinds of tools that we feel are essential for Modernist cooking, part of a well-stocked kitchen, or handy to have for special purposes. Our gear guide is a starting point. Not all of the available brands are listed; most of those given are the ones we happen to use in our kitchen, but others may be just as good.
