This sticker for the National Ice Cream Realtor Association really caught my eye.
They actually do have a website and an annual convention. They seem a bit old school. The convention in 2010 rated 20 small-batch vanilla and chocolate samples. Next year they're doing vanilla and strawberry. The testing is done by a professor of dairy science.
Where does judging of just two boring flavors by a dairy professor leave someone like Sweet Action who has a crazy menu including things like Chai, dark chocolate pomegranate, vegan colorado plum ice cream.
