How to make
Use a jug that has more than one liter capacity. Fill it to the brim with ice. Put the sugar on the bottom.
Squeeze the juice from the orange and add it to the sugar. Stir with a wooden fork. Open, measure and pour the champagne into the jug.
Add gin, vodka and stir. Leave it in the refrigerator for half an hour to cool well.
Don't forget to stir the cocktail before serving!
The Valencian Water (Agua de Valencia) is ready.
