Nothing, but I'm working up the gumption to make coffee ice cream. I'll steep whole beans and a scraped vanilla bean in hot sugary milk for an hour or two, then cook up that mixture with several egg yolks, and, finally, add a bunch of heavy cream and freeze the whole mess up. I'm making it decaf, so I can clog my arteries in the evening.
I'm also vaguely considering making a sour cream-based cake of some sort, since I have an extra container of sour cream kicking around. Moosewood has a good recipe for an orange cake that should work just fine.
