Slice the blood orange in half. Slice one half in round slices and squeeze the other half.
Pick a wide cocktail vase. Add 1 slice of blood orange to the bottom. Add the crushed ice on top, then another slice of blood orange.
Pour vodka on top. Then add the spakling water and the freshly squeezed orange juice.
Decorate with a slice of blood orange and the rosemary twig, serve right away. Cheers:)
You don't have to follow the same order in which I have added the ingredients. Feel free to shake your cocktail too. I live biting the orange slices once I'm almost done with the drink, that's why I like adding them in the order described in recipe instructions.
