First you need to prepare ginger syrup. Take the ginger root, peel and cut into strips.
In a saucepan, mix 300 ml of water and 4 tablespoons of sugar. Add the ginger, bring to a boil and reduce the heat to a minimum. Cook for 25-30 minutes. The syrup should boil by a third. Then it should be filtered and put to cool. This syrup in a closed container can be stored in the refrigerator for up to a month.
