oddly enough i wanted chocolate truffles in the middle of the day so i decided to save some money and use what I had around the kitchen. even odder was that i had the majority of the ingredients in my cabinet:
shopping list:
12 oz bittersweet chocolate (a bag of bittersweet choco-chips work just fine)
2/3 cup heavy whipping cream
1.5 tbl grand marnier (I did a little more)
pinch of coarse salt
some zest of orange
a small bowl of unsweetened cocoa powder (or powder sugar)
preparation:
over medium heat and in a small sauce pan, bring the pinch of salt, heavy cream, and orange zest just to a boil.
remove from heat quickly and add chocolate and the grand marnier.
stir until the mixture is smooth… you’ve made ganache! you could stop here and just eat but the fun part comes when you try to make martha stewart perfectly round balls! good luck.
chill the ganache until you can roll into balls.
roll into balls quickly then drop into the cocoa powder and chill.
my husband did not like the cocoa powder coating but i did. just the other day i had a truffle with sugar powder coating and it was slightly sweet and mixed nicely with the dark chocolate. i know it will pair very well with the grand marnier and maybe lighten up the bitterness of the orange zest. i am no cocoa-connoisseur but i am practicing.

I got to try one of these and I liked it. It is rich and the cocoa powder is not super sweet, but once you actually take a bite and all the flavors have a chance to introduce themselves it is a delight!

Oh summer had some and I tried to like them but the top was bitter to me.
