Just read your elderberry post, we got Sambucus Nigra around here with the same uses/preparations :) We make many liters of flower syrup, usually mixed with black locust flowers.
The dry flowers make very nice winter tea as well and it's been said to help with coughs in our folk medicine. We usually mix it with "whole-quince-tea", which is another cough/sore throat folk cure - the tastes compliment each other very well!
Is whole quince tea made from whole quince? I love quince! I will try drying some flowers this year, thank you for the recommendation @bobydimitrov!
Yep, it's a granny medicine :) Get a whole quince, wash thoroughly and boil in a kettle with enough water to cover the fruit and then some. Slow boil until the quince is completely soft and mushy. It usually is made with a few quinces in a larger pot and the boiling takes about an hour or more. Let sit until completely cold, the bring to a boil, take off the fire and add dried sambucus flowers and let them steep for a few minutes. Might as well post that :)
Sounds yummy! I canned quince in light syrup this year, sooooo tasty.
