Ingredients: 
* 230 grams bittersweet chocolate (I prefer < 70%; anything more I find too bitter)
* ½ cup brewed coffee (optional)
* 4 eggs, separated

Directions: 
1. In a double boiler, melt the chocolate and set aside to cool.
2. Separate the eggs.
3. In a medium size bowl beat the egg whites until peaks form.
4. In a separate bowl, mix together the chocolate, coffee, and egg yolks until well incorporated.

Merriam-Webster notes, "Recent criticism of the use of myriad as a noun, both
in the plural form myriads and in the phrase a myriad of, seems to reflect a
mistaken belief that the word was originally and is still properly only an
adjective.... however, the noun is in fact the older form, dating to the 16th
century. The noun myriad has appeared in the works of such writers as Milton
(plural myriads) and Thoreau (a myriad of), and it continues to occur
frequently in reputable English. There is no reason to avoid it."
