What's your favorite chocolate filling?

I'm working on my menu and am really looking for ideas from the masses (especially those who love to eat and gift chocolate).

Tell me what you love with/in/on your chocolate! Please be specific and detailed. Nuts, what kind of nuts. Fruit, what kind of fruit. Get the idea?

I'm also looking toward the next holiday season for some new ideas for mix-ins and combinations. This fall, I'm hoping to be a part of a few great local events such as Bedford Shop Til You Drop (aka STUD), the New England Holiday Craft Fair in Rockingham, community craft shows, the vendor show at Hampshire Hills, and more!

Let me know what you think!
