Pour vodka, lemon juice, orange juice, and simple syrup into the shaker.
Shake vigorously for 15-20 seconds until well chilled.
Strain the mixture into a chilled martini glass or coupe.
Cut a 2-inch strip of orange peel for the twist.
Hold the orange peel over the drink, yellow side down, and gently twist to release oils.
Run the peel around the rim of the glass and drop it into the cocktail.
Notes
Store fresh citrus at room temperature for best juicing results. Roll fruits on the counter before cutting to extract more juice.This cocktail works best with freshly squeezed juices. Avoid bottled alternatives as they can taste bitter and artificial.Make simple syrup by combining equal parts sugar and water in a pot. Heat until sugar dissolves, then cool before using.The drink can be made sweeter or more tart by adjusting the simple syrup amount between 0.25-0.75 oz.
