Whiskey Sour

So for my birthday I went to this bar called the Charelston and got a few drinks with a few friends. This other girl kept on ordering Whiskey sours all night, and since I was sitting right in front of where JR (the bartender) was pouring and mixing he joked with me that I was at the front of the classroom. I really was, before my friends showed up he'd talk me through what he was making. This is what lead me to order a Whiskey Sour, and what inspired me to try to make it myself last night.

What he put in them are: 1 pt lemon juice, 1 pt lime juice, 2 pt well whiskey, 1 pt simple syrup, 1 egg white, bitters. What I did was omit the bitters, I forgot to look for them at the grocery store, and I put probably about 2-3 pt whiskey (Evan Williams). So my recipe ended up being, for two short glasses:
1 oz. Lemon Juice (used 1 lemon)
1 oz. Lime Juice (used 1 lime)
1 oz. Simple Syrup at room temperature (used 2oz. sugar to 2 oz. water, I just stored the extra)
2 Large Egg Whites (I saved the egg yolks for cooking with later)
6 ish oz. Whiskey
6 Ice Cubes

What you need to do is mix the lemon juice, lime juice, simple syrup, egg whites, and whiskey in a mixer (or just an old clean jar works). Mix till you feel the egg whites coagulate. Strain into a glass without ice cubes. So easy! And so much tastier then a pre mix!!! The egg whites really give the drink a unique creamy flavour and a different texture to it.

The only thing I didnt do was at the bar JR dropped bitters around the edge of the glass and then stood a straw upright in the glass (because of the egg whites).
