This recipe is more like a giant prune turnover. This is found on many of the pueblos here in NM, and is a great dessert. The crust is more like a cross between a cookie and bread. This recipe is from a small pamphlet called "Sampling New Mexico Foods" printed in 1983, for the E. J. Martinez Elementary School. This recipe is definitely one for those who like to experiment. Many of the ingredients are approximate, as are the prep and cooking times. It's been years since I made this. I've usually seen it done such that the cinnamon is dusted over the top of the crust, instead of added to the prunes.
