Anyone know of any mexican candy recipes?

well, im not expecting anyone to know any exact recipes of any popular mexican candies such as Lucas and Pelón Pelo Rico but if anyone has tried to improvise or make us a recipe for the lucas im guessing that the following ingredients may be in it

1.) Chili Powder
2.) Salt
3.) citric acid
4.) Sugar

and thats pretty much all i can find
ive searched the internet trying to find a recipe
i dont want to go out and buy some because of traces of lead in the candy but
i absolutley love the stuff
anyother suggestions would be great also, like any tamarindo recipes and what not, thanks!
