Rose Petals

I had some roses which were withering and decided to pluck the petals and preserve it for later use like potpourri, or use it as floating petals in a glass bowl with a candle as a centrepiece on my dining table. Was wondering what else I could do with the petals when I recalled reading somewhere that flowers can be added to food recipes. So tried searching for some recipes online when I came across a recipe for rose petals ice-cream.
Here's the link:

I also came across several other ways rose petals can be used. Crush it, blend it to make rose beads; crystalise rose petals for use on wedding cakes.
