If it isn't Edy's Pumpkin ice cream, then it has to be Haagen-Dazs' Mayan Chocolate. Deep rich chocolate with a dark chocolate fudge swirl, and a trace of cinnamon. Something to behold.
I bought this ice cream this week, but to my horror, I see that it's been discontinued. Human sacrifice time (or run out to the store and buy up the last of it - just not in my town).
