Right around the corner from Poilane at 19 rue de Sèvres, sits an outpost of the venerable La Maison Du Chocolat.  For those in the know, this is the grand high temple of French chocolate.  In Paris, where finding the latest superhip chocolate boutique is a full-time job, La Maison du Chocolat remains refreshingly stalwart in their committment to offering simply the best chocolate.  They offer a variety of chocolates, pralines, truffles, and even pastries, but if you want the purest expression of chocolate decadence, I suggest you dive into the ganaches.  The quito ganache is an excellent example of what they do best.  It is rich, dark, slightly smokey, and intensely chocolatey.   And I always bring back bars of their baking chocolate to make the most velvety souffles and desserts.  No plans on going to Paris anytime soon?  Then check out http://www.lamaisonduchocolat.us/, they’ll ship.
