First, make a ginger infusion. Place the ginger and water into a pot with a lid on it. I use stainless steel Revere pots; glass and enamel pots also work well.
Bring the water and herbs just barely to a boil and then immediately turn off the fire.
Let the ginger steep for 1-2 hours.
Using a metal strainer, remove the herbs from the ginger infusion.
Add honey to the ginger infusion.
Add carbonated water to preference.
The shelf life of this ginger-honey mixture is 3 days kept in the fridge.
