Any of the above will work. Some even boil it in a little water and add during bottling. I tend to add it to the last 10 or 5 minutes of my boil. http://www.singingboysbrewing.com/sweet-stout.html

I usually add it during the last 15 minutes of the boil.

i've always added at the end of the boil. just enough time to dissolve it.
