There are a couple of dark chocolate bars out there with chili bits. Lindt makes a good one. It's a powerful taste, and I think there's only enough sugar in it to hold it together.

Expresso-flavored confections might be another option, or something infused with scotch or brandy. Maybe a berry sorbet of some kind.

That Chateau D'Yquem sauterne he had in 9.9 is a dessert wine. Don't be too eager to run out and try a sauterne, cheap ones can be awful. He might like a Rheingau Eiswein.
