Pretty necessary, unless you're on that weird "all carrots" diet. And if you are, I don't know how you ended up on a shopping website, and specifically on a kitchenware sale. So I'm comfortable assuming that you are not one of those people, and are in fact a normal person who likes delicious food, and especially likes it when it's prepared well, and even moreso when it's prepared safely and cleanly. And since my assumption is correct, you're in the right place to empower your own food preppery with all sorts of nifty gear, gizmos, and gadgets.
