This Flourless Chocolate Cake Is Impossibly Rich and Creamy
To make the tomatillo sauce, remove the husks from the tomatillos, rinse them under cold water, dry with a towel, and coarsely chop them. Put them in a pot, scrape the vanilla bean into the pot and add the pod, and add the piloncillo, water, sugar, and canela. Cook over medium heat, stirring from time to time, until the tomatillos are very tender, 15 to 20 minutes. Remove and discard the vanilla pod and canela. Transfer to a food processor and purée to the desired consistency (completely smooth or a bit chunky). Let cool. (This can be made up to a week in advance and stored in the refrigerator in an airtight container. If it is too thick, add a bit of water until it is a pourable consistency.) Serve slightly warm or at room temperature.
