Help! Truffles, need truffles.

I am in search of the perfect chocolate truffle recipe. I totally want to try something with a little bit of a spicy kick to it. I'm in the process of getting some ideas. I made some a few days ago, but used too much unsweetened chocolate and not enough of the sweet stuff. So I improvized a bit, and added toffee candy bits, mixing in each truffle ball and rolled in powdered sugar. This is just a first effort. Any suggestions?
