Some may ask why not use the electric blender. It is too efficient and I think, the rose oil preserves better in bigger fragments of the crushed petals which can always be blended later preparing desserts, drinks, cakes, whatever. My advice is: do not overdose. Some people find the smell of rose oil too strong for their liking. In this case less is more and more is less.
Rose petals are great to prepare a home made liquor. I will share the recipe soon, I promise.
