Looks tasty. I was kind of hoping that based on your name it would have been pepper topping of some sort.
My wife got me into using Cacao powder on my vanilla ice cream.
Not a topping, but a flavor of ice cream that I really enjoy is Snoqualmie brand's Blueberry and Cardamom. It sounded weird, but after the first bite I was hooked. Too bad it doesn't come in the large tubs.
