Boreal Curing

All that unsulphured molasses is. is molasses that does not have ADDED sulphur. All molasses has some sulphur naturally. Some companies add sulphur to restrict yeast/fungi. Just ask if it is added. I've never used sugar but some do.
I use Turbinado Sugar (natural brown sugar) in my supersoil, and a bit at planting time. But beware, adding sugars at planting time will invite ants which acidify the soil, so dolomitic lime is also added.
