In my mad hap shopping manner I ordered in everything or so I thought, expect sweetener. Is there something that might be available locally I can use?
you can buy large bottles of Sucralose at tops its in with the sugar replacements.
Do you have any sweet flavors? Like Cotton Candy, or Butterscotch, or Caramel, or Marshmallow?
You can use those as sweeteners too.
The powdered stuff is 99% something other than sucralose. What, I dunno ... but my guess would be anti-caking & preservative additives. The pure sucralose is marketed as Sweetzfree, EZ-Sweetz and others. Google it, because it's only available online.
