Add a scoop of fresh ice to a highball cocktail glass.
Pour in the vodka and orange juice.
Stir the ingredients with a bar spoon to mix well.
Add a couple of dashes of orange bitters.
Add a couple of bar spoons of simple syrup and stir again.
Lastly, give a spritz from a seltzer bottle or pour some club soda into the drink to give it a little sparkle.
Notes
If you don't want to squeeze the oranges yourself you can use a store-bought brand, but pick one that is low in sugar and features some pulp for an authentic taste.You can muddle some orange peel in the cocktail glass for an extra-intense taste.
