Can Rose oil be used in cooking?

Buy food-grade rose oil.

I recently made some Turkish Delight and added some rose oil.. just 2 drops.. it gave a lovely fragrance and nobody had any side-effects. So I would say that you could safely use it occasionally, but very sparingly! ;)

:) :) Guys, you sounds really funny about the rose oil. I do not know what exactly you've bought, but if it's organic, that mean you will never have any problems. I've drunk a lot of the Bulgarian Rose water, becouse it is good for million things in my body. I use it a lot for cooking and cocktails making, so do not worry to use it in whatever you feel. You can read here about the health and Pharmacological Effects of the famous Bulgarian Rosa Damascena: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3586833/

Oils, or any substance for that matter, which is not food safe must be labeled Non GRAS - not generally regarded as safe. In this country, at least. You were right to question the rose oil. At least you likely aren't out a significant investment.

Don't use it for the cookies or any food prep. This oil was not intended for internal consumption and has been labeled as such. You don't know how the oil was purified and what was used in its processing method (eg. other chemicals, machinery, possible metals, etc). You can get very sick, or worse, with minuscule amounts of the right substances.

I have a degree in chemistry and was in pharmaceutical R&D for 8 years. In my freshman year of chemistry, the professor told the story of the student who died from drinking distilled water that was in the lab. The water itself was clean. It was the container that he drank from that was the problem. The container, a glass beaker, had some residual preservative on it's surface which was enough to poison the student. Even that residual thin coating on the glass was too high of concentration. So 1 drop may not seem like much, but it can potentially be more than enough to do harm.

I don't want to be such an alarmist, but better safe than sorry. If you want to use rose oil for these cookies, find one that is labeled 'food grade' or 'safe for internal use'. Use this oil that you have for perfume or potpourri.
