Add elderberries, cinnamon, ginger, cloves, lemon peel and water to a saucepan.
Bring to a boil, then reduce to medium heat and simmer until the liquid has reduced by about half (approx. 25-30 minutes).
Remove from heat and let steep for another 5 minutes or so.
Then strain out the solids and reserve the liquid.
Add the honey to the liquid and stir until dissolved.
Transfer to a bottle or jar (a Mason jar works well) and store in the fridge for up to 6 months.
