...did you discover recently which has made your life better?
For me, there have been two: the cast iron skillet and the Yukon gold potato. I'm sure you all know this already, but it's new to me. A non-stick skillet which you can get solar-flare hot: priceless. Use the thing constantly. And I heard of the Yukon gold in Iron Chef America and decided to try it. I was initially skeptical, since it's a potato: how great can it be? But I love them.
