My Mum taught me how to do these when I was about ten years old - I remember helping her pick the roses! I try to have a good store of crystallised rose petals, as they are such an imginative, beautiful and edible decoration for cakes and desserts etc. Make sure your rose petals are free from pesticides and are not traffic polluted either. The more the fragrant the rose, the more fragrant the taste when you eat them! I have given these as gifts before, in an attractive tin and with an attached recipe hanging from the ribbon - unusual and yet edible! They are wonderful as decorations for my Recipe #183505.
