We're getting married (yay!) and will be registering soon. We're both adults with the basics, but would like to upgrade and get new, cool stuff. The websites that tell you what to register for seem geared to 20-year-olds. What sort of things have you received that have been really useful or have become "must-haves"? You're all so experienced with such good advice, and I know you can think of things to help make us better cooks or at least to make the time in the kitchen smoother/more fun.
