1/2 oz of Tequila
1/4 oz of Gin
1/4 oz of sweet and sour mix
1 dash of Lemon Juice
1 dash of Angostura bitters
1/2 oz of Triple Sec
1 oz of Vodka
Add everything but the bitters and lemon juice to a blender with four ice cubes. Blend for less than a half minute (the ice cubes should not be totally disintegrated). Pour into a highball glass, add the bitters and lemon juice, and serve.
