Rub the peel of a lime and set the peel aside. Squeeze out all the limes and weigh the juice. If the juice is less than 130 g, top up with water.
Bring the juice and sugar to the boil in a small saucepan, simmer for 1 minute and then let cool down a little. Peel the mango. Put the coarsely chopped pulp in a higher mixing bowl and puree finely. Stir in the grated lime zest and the sugar juice. Now mix in the vodka.
Fill the limes into a bottle and close tightly. It keeps in the refrigerator for 5 days.
