Directly inspired by the Angostura Bitters Ice Cream that we had at Sage (Las Vegas) last month. You could say that this ice cream flavor is almost like an Old Fashioned cocktail ice cream but with the aromatic bitters as the main flavor instead of the whisky. Having become a bit obsessed with Armenian fruit preserves lately, my original plan was to mix in some Maraschino liqueur-soaked Ararat Sour Cherry Preserves but unfortunately these had pits in them. I went with the expensive choice of Luxardo cherries instead - always so good. If I make this again, I would add more citrus zest.
