Boil the water together with the sugar until the sugar has completely dissolved. Depending on your taste, you can of course use more or less sugar.
Meanwhile, scrape off the peel of the ginger with a teaspoon. This way you don`t lose too much of the ginger and you don`t accidentally cut yourself.
Now rub the ginger completely with a grater. Let the grated ginger boil with the sugar water for 10 minutes. If necessary, boil the end pieces of ginger that could no longer be grated and simply fish them out at the end.
Rub the peel of the lemon, squeeze the juice of the lemon and oranges. Add the juice and zest to the boiling ginger water and cook briefly.
This drink tastes hot and cold. A real vitamin bomb, especially in winter!
