Put your dried elderberries in a pan with water (I use about 2 cups of water for 5 teaspoons of dried berries). If you feel like it, add a few slices of (organic) lemon and bring to a boil (I explained in my other elderberry post why boiling the berries is a vital step). Let simmer for about 10 minutes. Watch the colour come out and then close your eyes and notice how your kitchen smells like a magic elderberry forest.
Strain and drink. We like this just the way it is, but some people like it sweeter than that. You could add stevia leaves to the brew, or raisins, or some dried apple. Or add a teaspoon of honey in the end.
Another idea is to add some cinnamon sticks, orange slices and dried apple slices. I've done so in the past and it makes a great alcohol-free Glühwein alternative.
