Start by heating water and dissolving sugar in it. Allow the mixture to cool to room temperature. In a jar, combine the sugar water with diced ginger. Seal the jar and let it sit at room temperature for 1 day.
Over the next 5 days, stir in a teaspoon of sugar and 15 grams of ginger into the jar each day. When you observe bubbles, your ginger bug is ready to be used. Incorporate the ginger bug into a juice or tea, maintaining a proportion of 1 part ginger bug to 10 parts of the other liquid for a delightful and flavorful beverage.
