Here's a way to separate the diehards from the dilettantes in the chocolate world: offer a taste of Slitti's GranCacao 100% Cacao bar. Untempered by sweetness or creaminess, it certainly is an acquired taste. A little goes a long way, too, so it's great for garnishing.

The Tuscan chocolatier also makes gentler dark milk chocolate Lattenero (70% cacao) and single-origin 90% bars like Amazzonia from Venezuela...  Stylish novelties include solid chocolate spoons to stir coffee lovers and chocolate tools to tempt handy men.

Look for them in fine food shops...
