If you don't have or can't find raspberry-flavored sugar, turbinado works well.
The Nielsen-Massey brand of rose water is quite different from the more traditional Middle Eastern rose water. I wouldn't swap the two.
Since scones taste best the day they are baked, I like to store them raw in the freezer and bake off a few at a time. Keep them on the baking sheet until frozen solid, then transfer to resealable plastic bags and seal well. You may need to add a few minutes to the baking time.
