Just pick as far back as you can snap off, so that it isn't woody, then boil for only one minute or saute in oil or butter - garlic added at will! We had the last lot with the flower buds from kale and purple sprouting broccoli, stuff that most people would discard.
I don't like the furry back taste of nettles either, which is why I dry mine and tend to use it out of season, although fresh, as a tea, it is very nice once strained.
