Chocolate Hazelnut Torte. This torte is a classically dense, rich dessert. The darker the chocolate you use, the more intense it will be; I prefer 70% chocolate, though you could use 63% if you like, or semi-sweet, or even milk chocolate if you're of that ilk. Hazelnuts rounds out this cake with a wonderfully toasty flavor, while a healthy dose of vanilla provides a gently sweet aroma to balance out all that dark chocolate. I add a touch of cinnamon for a little something-something.
