This was delicious! I followed the recipe exactly with a few minor changes. (1), I used Nestle's semi-sweet mini chocolate chips and reduced the amount of white sugar to about 1/3 cup. It still very rich and plenty sweet. And (2), I heated the chocolate chips in a double boiler to avoid burning the chocolate (a glass heat-safe bowl holding the chocolate chips set on top of a saucepan with a small amount of simmering water).
The mousse was set firmly within 4 hours, although it may have set in less time than that, since I didn't check on it. Using 6 oz. glass custard cups, this recipe makes 8-9 servings. I will absolutely make this again.
