Rose water is used in amost all sweets, desserts, puddings; in the south, folks add rose petals to their spice mix called kammooneh. In the Gulf countries, rose water is even added to rice dishes; it is sold in all the ethnic markets or health-food markets in the US; rose water is supposed to be a great skin tonic. It was applied to soothe skin burns. It is used for religious purposes.
The only problem is this: Is the bottle of rose water, really, distilled rose water?
In most cases, no. It is water flavored with rose essence.
The solution is to plant a rose bush in your yard and distill the petals yourself. Not any rose bush, though. Rosa Damascena.
