I don't know if anyone knows about this--I just stumbled upon it and I haven't seen it on Chow--but I thought this was pretty cool:
It's a recipe tool by David Leibowitz that allows you to choose infusions, flavors, and mix-ins for homemade ice cream. After you do that, it shoots out a recipe for you to follow!
Helpful for people who are ice cream making newbies, but want to venture beyond single-flavor ice creams.
Hope this is helpful to someone!
