*Choose the best quality chocolate you can, as the flavor really carries the drink. I love Guittard for a splurge, Ghirardelli, or Godiva, but the Trader Joe's Pound Plus 72% bar is quite good too. I do not recommend chocolate chips, as they contain stabilizers and do not melt as well. Leftover French hot chocolate can be cooled to room temperature, then refrigerated in an airtight container (empty mason or jam jars work particularly well). Reheat gently the in the microwave or in a saucepan over low heat.
