When I was a little kid, my mom and I once made dumplings/potstickers with this neat white foldy press (that helps crimp them together). There's a really cute picture of me at about 3 years old, standing on a step-stool, wearing an apron, and proudly holding up a potsticker.
Anyway, on a recent visit to Los Angeles, I saw the potsticker crimper sitting in a drawer (probably unused by my mother since that day in the photo), and asked if I could take it home. (I subsequently saw the exact same crimper for sale at Hill's Kitchen about a week later, but oh well.) With the proper implement in hand, and having just acquired a "Cook's Illustrated" recipe for perfect potstickers (compliments of Jon's mom), we went to making potstickers.
The recipe that follows is a combination of the Cook's recipe and the handwritten one my mom had from an Asian cooking class she took long ago. No doubt that is the recipe I followed at age 5.
