Rattlesnake

From Beretta in San Francisco. Simple twist on a sour that's very tasty.

2 oz Rye
1 oz Lemon Juice
1/2 oz Grade B Maple Syrup
1/2 oz Egg White
2 dashes Peychaud

Combine all ingredients in a glass and shake for 5-10 seconds. Add ice and shake for 20-30 seconds. Strain into a cocktail glass and garnish with a lemon twist.

Enjoy.
