I don’t want to play down the seriousness of OCD as a condition that many have to deal with, but if you’ve ever tried to really learn the knife skills that classically trained chefs have used for generations, you’ll know that a small element of OCD might actually be helpful in mastering them. OCD in this case, of course, stands for “obsessive chopping and dicing,” and the The OCD Chef Cutting Board helps you to practice exactly these skills. The wooden board is laid out with a measured grid that helps you get the perfect large, medium or small dice and even tiny brunoises (1/8-in or 1/16-in square cubes), as well as juliennes and batonnets when you are chopping. The board alone isn’t going to have you chopping up vegetables with the ease and speed of a Michelin-starred chef, but it does mean that you won’t need to eyeball the measurements and hope that your dice are all the same size for even cooking. And if you have a sharp chef’s knife and a bag full of carrots, onions and potatoes to practice with, you just might get both that speed and that prevision down with a little help from the OCD board.
