Peppermint Lace Cookies
Crushing peppermints or candy canes: you can put them into a resealable plastic bag and beat them, or you can put them into a chopper/processor and process to fine. I then put them through a fine wire-mesh strainer. The powder that falls into bowl is for final sprinkle mixed with a few tablespoons of confectioners' sugar; the pebble size is for inside cookie dough.
If you have trouble removing cookies, try cupping your fingertips over them to move the whole cookie loose.
