As I am well versed in Ben and Jerry's ( I worked there for 7 years) I can tell you we lost our fair share of kick ass flavors to non popularity with the mass market. One of my many favorites was Chocolate Raspberry Swirl.
And incidentally Jill, there were 2 different formulations of Wavy Gravy. The original was way sweeter than the 2nd, it was a caramel brazilnut ice cream with caramel swirls and chocolate covered toffee chunks. The 2nd (and my preferred wavy) had chocolate hazelnut swirl.
Ahh...the good old days.
