I had to put the subtitles in Spanish because I didn't understand what they were saying. It has goat fat and lard, garlic, parsley, cinnamon and pepper and they also add a little oil so it can be kneaded. I find the cinnamon thing curious. And to make it, I don't know if I'll be able to find goat fat, but I can find lard, which is easy to find.
The documentary is from 1997, and I suspect that there is no one left who makes this recipe.
