Income tax cocktail

I read about this on AccountingWeb recently and then checked it out on Google. It's a variation of the classic Martini with orange juice and Angostura bitters added.

Ingredients:
2 oz gin
1/4 oz sweet vermouth
1/4 oz dry vermouth
1 oz orange juice
Angostura bitters to taste
Orange twist for garnish

Method:
Pour all the ingredients into a cocktail shaker with ice cubes and shake well. Strain into a chilled cocktail glass and garnish with an orange twist.
