You must be careful when purchasing rose water to buy only the 100 percent pure form. Often what is available in pharmacies and even some natural food stores is synthetic rose oil and water with preservatives added. Pure rose water is the distilled water of roses. It is usually made by stream distillation, and it smells heavenly and tastes delicious.
Availability: Besides health food stores and herb stores, you can often find rose water in delicatessens; it is used as a flavoring in fancy Greek pastries, puddings, and cakes.
This recipe is the more traditional way to prepare rose water. Though it’s a little more involved, its fun to do and the results are outstanding. You can make a quart of excellent-quality rose water in about 40 minutes. However, if you simmer the water too long, you will continue to produce distilled water but the rose essence will become diluted. Your rose water will smell more like plain distilled water, rather than the heavenly scent of roses.
