In working on nearly all 100 issues of Observer Food Monthly, our food taster Caroline Boucher has had the opportunity to munch through hundreds of delicious things (and some less than delicious things as well), and she also made it her personal mission to try out all the gadgetry that came into the office, so you can be sure that the 50 favourite things she's picked out to be featured in the 100th issue of OFM are the very best out there.
