As befitting a diner dessert, this ice cream is thick and rich and perfectly accents the apple tartlet. Cinnamon ice cream generally falls into three categories: infused via cinnamon sticks during the milk warming; ground cinnamon added during the milk warming; and ground cinnamon added at the very end. You can't get a real cinnamony flavor from the sticks alone, and adding ground cinnamon too early makes for a very strange texture. The third option lends a nice flavor and texture and leaves the custard pleasantly speckled.
