Truffle Guy, I was happy to see that: I have been starting my ganache with melted tempered chocolate for some time now, with good results. I've been wondering whether I was alone in that, and whether it was considered a no-no. ← You're not alone, I started out using the 'hot cream to melt" method with o.k. results. Then the "cream to premelt", I would still get a grainy texture, every now and then. Now I add my cream to tempered chocolate in liquid state. I don't don't know if this is science or superstition. So, I'm guessing the tempered chocolate jump starts the proper crystallization. I've never had a grainy mixture since. The only adjustments I've made is to use a plastic bowl instead of metal for mixing. I found it a pain when the chocolate would start to set on the inside of the metal bowls.
