I remember a similar "cookie" from the days of my youth. Our family made small anise flavored cube shaped cookies about the size of a sugar cube. Hard as rocks if memory serves.
No idea what they were called. Sounds like a similar thing though.
"I must say as to what I have seen of Texas it is the garden spot of the world. The best land and the best prospects for health I ever saw, and I do believe it is a fortune to any man to come here."
Davy Crockett, 1836
