Add 2 quarts of fresh elderberries to a pot with 1/4 cup of water.
Let the berries simmer over medium-low heat for a few minutes until they are soft and release their juices.
Use a potato masher to mash the berries.
Remove the berries from the heat and strain them through a sieve, pressing to extract as much juice as possible.
Measure the juice and return it to the pot.
Add ginger root, cinnamon sticks, cloves, and nutmeg.
Simmer the juice over medium-low heat, checking periodically until it has reduced by half.
Remove the juice from the heat and strain again. Measure the juice.
Measure out the same amount of honey as juice. Using a spatula, scoop the honey into the hot juice and stir until combined.
Bottle and store in the fridge, using as needed, by the teaspoonful.
Ideally, use this within 3 months; however, because of the amount of honey in it, mine has kept for quite a few months. Use your best judgment.
