Black....I am not sure either. I know folks use rose hips for a tea....but look here at this SMF link.
Hope someone else will chime in soon!
I'm guessing it would have a rather floral flavor.
Sorry I couldn't resist. In all seriousness, Glenlivet makes an 18 year old single malt aged in roserood that's absolutely fantastic, so at least we know it has some culinary potential.
You certainly sparked my interest so I did some searching and found this info:
Roses grow in slim canes that and with age can become woody and most commonly grow as bushes.
Rosewood does not come from Rose bushes, but it does have the rose scent when in bloom.
The wood is cut from several different tropical trees.
Rosewood is listed as an irritant, because when sanding it can cause allergic reactions.
My first thought is NO. I don't imagine it would really season very good. You could try burning some on an open fire and see what the smoke smells like. I wouldn't burn it in my smoker until I knew what it smelled like and if it leaves any kind of skunky residue that would require cleaning the smoker.
