I made some delicious elderberry syrup the other day with elderberries i foraged. I froze them first to make them easier to remove, and then juiced them once i picked them off the stem and got rid of most of the twigs and stems leftover. Then i juiced them along with an apple and some ginger, and simmered with honey, boiling it down until it was a nice syrup consistency. Awesome in greek yogurt, or on waffles.
