Rose Water?

Are there any regular drugstores or markets that carry rose water?

Not sure what you mean specifically by regular stores. What's your location?

Many gourmet/natural type markets carry it, as do a number of "ethnic" markets, particularly Middle Eastern, Indian, South Asian in general. You can find it by the spice/baking areas in places like Whole Foods.

There's a difference between rose water and rose hydrosol. Hydrosol is the quality stuff with all the EO properties. Rose water is just rose oils (and other stuff) diluted with lots of, ehh, water... Price difference is pretty big, OC.
