Advent Calendar - Sidecar

I've had this bottle of Armagnac for about a year now, and I've used it a few times in place of vermouth for a manhattan, but I really didn't know what else to do with it.  So, thanks google, tonight we tried a sidecar.

I mixed 3 oz Armagnac, 1-1/2 oz Gran Gala Orange Liquor, and 1-1/2 oz fresh squeezed lemon juice in a shaker.  Shook the heck out of it, and poured into chilled coupe glasses with a twist of lemon.

Joel and I agreed it was tasty but, a little tart.  Honestly I never get heartburn and stated, this tastes like heartburn.  So, it's not going to be our new favorite drink but we both agree it was worth a try.
