My Mom used those candies. She also used a low cal ice cream made by Metra-Cal. The chocolate was a strangely bright color of brown. We kids were not to eat it.
Did you want to eat it?
My mom tried it too, and yes, it was OFF LIMITS!!!!!!!!!
The Wikipedia article said it lost popularity when it was linked to deaths.
I also see they have a gay ice cream brand at the market. Not sure what that means.
