**MF Dark Chocolate I used is the Silver version, but I don't see it in the database. Supposedly the silver is even stronger than premium/platinum. Considering bumping it up to 0.5 or so if using the PG version.
Bourbon or Brandy - to liqueur-fy the huckleberry.
Mousse & Clotted Cream - to truffle-fy the chocolate.
Chai - for a touch of punch and spice, goes better with the chocolate than a citrus. I suspect FLV Chai Spice would work a little better here, but I didn't have any and BCF was out. Ginger would also work if you had it.
Sweeten to your tastes. None of the flavors have much inherent sweetness, and it is a dessert...
