Why not try making it for yourself?
I am trying to remember the ingredients:
Find a site that tells you how to make various kinds
of candy like soft, semi-hard, hard.
Any appreciable heat turns sugar to caramel and there
was no caramel-type flavor or consistency; so, I think,
very little heat, if any, is used.
I love caramel, but it is not good for survival:
1)pulls fillings and caps off of teeth
2)harder to digest
Maybe Kendall Mint Cake is constipating also, though I
doubt it. I never ate enough at one time to find out.
