Resources for specific ingredients below: yes, it's a ton of dried rose petals, but I took the plunge and bought the 1lb bag. It will last forever but I figured why not. I can rose petal up EVERYTHING now. Watch out! Also, here is a great pistachio extract. You don't have to use pistachio specifically in the cream cheese frosting. Vanilla, extra ground cardamom or even rose-flavored extract could work beautifully. I heavily considered each option but opted for the pistachio for an extra punch.
