Found this recipe on line a few years ago and really like the way this syrup tastes, especially on buttermilk waffles.  Easy to freeze or can.

 I remember having chokecherry syrup when I was growing up. Brings back great memories.

 If you boil it a little longer, to the hard crack stage, you'll have chokecherry candy, which is very good.
