Rose water is essential in Turkish delight, and I have used it in fondant to make sweets. It's nice in some cakes, and one of my favourite uses is in rice pudding. I am actually allergic to roses and it makes me sneeze, but don't care!!!
Rose water is also very common in Indian desserts. My favorite dessert, gulab jamun, uses it, as does kulfi, an Indian version of ice cream. In Hindi, the word for rose is "gulab."
