Oh Kitchen Aid, oh Kitchen Aid, how lovely are your features... This thing is amazing. It kneads dough, whips cream and egg whites (meringue, how I love thee), and creams butter in the flashiest of flashes. If you already have a Kitchen Aid, I've heard great things about the ice cream maker attachment. (I have heard equally lackluster things about the pasta machine attachment, but to be fair, I have never tried either one.)
A couple of different thermometers for you to consider. On the left is a simple one that hangs from one of the shelves in your oven, and tells you the actual temperature inside! The temperature gauge on an oven can have a 10- to 15-degree swing, and do you really want to risk that when you're baking? I didn't think so. The little one on the right is great for roasting meats - stick the probe in, set the digital part on the counter, and close the door. No more opening the door and letting all the heat escape while you poke the meat (and release the juices!). You can even set an alarm that goes off when the inside of the meat reaches the desired temperature. Done and done.
A Microplane grater/zester. I finally bought myself one, and used it for the first time last night. Oh. My. Gosh. I can't tell you how many times I have accidentally grated my knuckles while trying to zest a lemon or grate some fresh ginger. If only I had known sooner that for ten measly dollars, my fingers could be saved... This thing is a miracle. Get it.
Tongs! Another amazingly useful tool. Before I had these, I didn't know I needed them. Now, I find myself reaching for them all the time. My favorite use for them: tossing hot pasta in a homemade sauce.
This past weekend, I was rolling out the dough to make the butter horns (our homemade crescent rolls), and I was getting flour all over my black shirt (BLACK?! What was I thinking?). And then I remembered that old-timey stroke of genius, that item of clothing that has been worn by generations of women, but somehow forgotten by ours, THE APRON. I have one, but I don't wear it, because it's indecent. It's me as Venus. It's... funny and scandalous. So it's basically like I don't have one. But! I want one and I love the ones they have at Anthropologie. They're are whimsical and sweet.
