In a large bowl mix the flour with 3/4 of the lard, meanwhile heat the achiote with the rest of the lard. Stir in flour, sugar, salt, water and sift. Once well mixed, knead until the dough has an even consistency. Divide into balls the size of your hand closed and let stand with a plastic covering overnight to allow dough to rise. But if you do not have time for that, you can prepare this in one day.
