I've also used demerara sugar (raw cane sugar) with a flavor like light brown sugar laced with honey. that worked well. Palm sugar works too I hear. Some even use that spiced mexican sugar that comes in cones. I use corn sugar (dextrose) most of the time. Just dissolve them in 2C of boiled water,cover,& cool abit before priming. I think the 2C of water thins it down better.
