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 :)
