Before you begin you'll want to scrub the oranges to remove any wax on the skin. Place the oranges in a bowl or boiling water, leave for a couple of minutes and then scrub with a brush to remove any wax before rinsing under colder water. Dry the oranges and carefully remove the skin, removing most of the pith. Add to a large jar along with the vodka and cover and place in a cool dark place for 48 hours.⏱ 2880 min
Juice the oranges and place in a medium sized saucepan along with the sugar and water. Stir to dissolve and then place over a high heat and bring to a boil. Cook, without stirring, for 3 minutes, or until the mixture thickens slightly and set aside to cool.⏱ 3 min
Strain the vodka to remove the peel and discard the peel. Combine the vodka and syrup and pour into sterilised bottles.
