Apart from the invention of the stove, cooking hasn't changed much in the last 100 years or so. Yes, food fads come and go (you hear that, kale, I'm talking to you!), but overall the methods remain the same. That's why I get so excited about cool kitchen gadgets. Anything that makes the day-to-day humdrum of cooking more convenient, less annoying, and, dare I say it--fun--is an instant purchase in my book.
