My elderberry bush is getting pretty big and producing a lot of fruit, so this year I took advantage of it.
Boil berries in water
Sweeten to taste with honey
Pour over ice
There's a neat trick to separating the ripe berries from the stems: Put the bunches of berries in the freezer for 10-20 minutes. Remove the bunches one at a time and gently roll between your palms over a baking sheet or a large bowl. The berries will fall free.
