Hey, don't knock it too hard. It's better than sodium saccharine (which is 1,000 times sweeter than sugar) and aspartame (which you cannot cook).
Splenda is nothing less than a godsend for us diabetics and pancreatic cancer survivors.
I got my diabetic grandmother switched to Splenda. It's all she ever uses in baking and in her breakfast cereal.
Matter of fact, I'm not a diabetic and I think Splenda tastes just as good as pure sugar. Even the sugar-free candies she buys tastes as good as the sugar-loaded candy to me.
