Tullamore Dew Old Fashioned

Tullamore Dew Old Fashioned I was looking for an excuse to use my lovely Tullamore Dew which I reviewed here and it occurred to me that I've yet to make a whiskey Old Fashioned. I've made one with rum, but haven't done a proper whiskey variant. Admittedly, this is still breaking from tradition slightly, in using an Irish whiskey instead of a Bourbon or Rye, or anything American really. But this is not too far off base. Unfortunately, I didn't have any oranges to get a swath from, but this is a brighter whiskey, so I think we should be okay. The angostura bitters are very forward on the nose, there's some appley notes as well from the whiskey, but it's a lot of nutmeg and cinnamon and maybe a little allspice, it all leads to a very pleasant baking apple smell. Sort of a moderate mouth feel, not thick or thin, not sharp or anything, but I've had smoother, and then as you're dissecting the feel of the drink, the flavor creeps up on you, like war...
