1/2 egg white (weird, I know, like who has half an egg white lying around?)
few drops peppermint flavouring
1 Tbsp lemon juice
Place everything in a food processor, and let it churn into a smooth ball. Take out, divide in half. (We dyed one half blue, then rolled out strips of white and blue and rolled them together: looked like weird but cool candy canes) If you want to dye them red or green for a more festive look (or if you've hit the eggnog earlier than usual and are feeling a little wild'n'crazy), do it now. Don't use too much food dye or it might look a little too lurid for your guests.
Then you can either roll them out between parchment (careful, they tend to be sticky) and use tiny cutters (finally, a use for all those Playdough shapers!), or roll them into ropes and slice tiny pieces off. Then place them on a cookie sheet and let them dry overnight.
