Melt your chocolate according to package directions. (Remember that if your chocolate isn't thin enough you can add a little vegetable shortening to it. Never add water, it seizes up the chocolate.)
Add peppermint extract to your chocolate.
Dip Ritz crackers in chocolate and remove to wax or parchment paper to harden.
If you want to add the crushed candy canes, sprinkle on top of chocolate while still wet.
