I think paisleyblue's interpretation is very elegant.
for the sake of exhaustion however, i'd like to point out that there are a few kinds of ice cream that have a black color.
Probably the best candidate is licorice ice cream, which seems to be rare to find outside of the midwest. It seems like it's most often homemade since it's a traditional dish and is probably an acquired taste. JD has a preoccupation with the midwest so i think this is a strong possibility.
There are also a few japanese ice creams that are black in color, including one containng crushed sesame seeds. Since this is an older recipe it apparently has a taste and texture very different from what is normally thought of as ice cream. Also it stains your teeth black.
