I did indeed go back for it. The custard ice cream base is very creamy and lightly flavored. I think a vanilla ice cream would have overwhelmed it. There is also a caramelized sugar swirl that lends itself well to the sweet, mellow flavor. It actually reminds me of some of the dulce de leche ice cream I've had with small, gritty chunks of crunchy sugar. It was very good, but very sweet and almost cloying after a while. Still, hits the spot.
I picked up a package of Hershey's Extra Dark with Pure Espresso. It's 60% cocao with bits of espresso embedded in the squares. Dude. They're little packets of unadulterated joy. Smooth dark chocolate and gritty, crunchy bits of coffee. They're good.
Sorry for the brevity of this post. Someone was being selfish.
