I eat them raw by careful nibbling off only the outside, and avoiding the furry center. So much like an artichoke! Easier to do with nice large rose hips like on a rugosa rose
I also make syrup from them. I tried making jelly one time with that no sugar pectin, but I guess I didn't do it right, because I ended up with a bunch of amoeba shaped gummy bears, in syrup. The gummy bears were tasty, and I canned the syrup, but I haven't tried jelly since
