It's also a perfect homemade holiday gift, and much cheaper when you make it yourself.
Step 1: Gather tools and ingredients
peppermint1 candy (Candy canes, sticks, whatever you can find that's cheap and tasty.)
1 pound chocolate (dark, semi-sweet, or milk)
1/2 pound white chocolate
food processor, blender, mortar and pestle, or bag and heavy whacking object
2 glass or metal pans, 9"x11" or larger
1Note that it doesn't have to be peppermint- this recipe works equally well with any hard candy, so peppermint haters should feel free to substitute spearmint, cinnamon, or fruit candies as taste and availability dictate.
Step 2: Prep pans
It should curl up to protect the sides, too. Crease the corners so it behaves.
Step 3: Crunch peppermint candies
I used a food processor, but you could use a blender, a plastic bag and heavy whacking object, or even a mortar and pestle.
Whir or whack away, making sure to break down all of those big pieces into small-enough chunks. You can dump out the small bits then re-process the big ones until they're useful.
Mechanical means will likely produce a fine powder as well (we call this "weaponized"1 peppermint), which you'll want to separate from the small chunks by means of a sieve. It's too fine to sprinkle on top, but is great for adding directly into the chocolate for extra pepperminty flavor.
1 Do not inhale powder. It burns the mucous membranes. And no, it's not anthrax.
Step 4: Melt chocolate
Microwave in 15-sec bursts, stirring between. Total time will vary depending on quantity of chocolate and microwave strength, but it's still only a couple of minutes.
Optional: stir in bits of weaponized peppermint for extra kick.
1Water interferes with proper chocolate-melting, so keep it out of your bowl!
