It's also found in Extremadura, where it is known as buche or buche de costillas.
This type of Embutido/Enchido is a meat product made from different pieces left over from the butchering of a pig, including the ribs, tail, and bones with a little meat left on them. These are chopped; seasoned with salt, pepper, garlic, and other spices; stuffed in the cecum of the pig; and partly cured via smoking. It can also include the pig's tongue, shoulder blade, jaw, and backbone, but never exceeding 20% of the total volume. It is normally consumed cooked, covered with a sheet. Flavored with Chorizo/Chouriço/Chourizu, the pig's ear and snout together with very tender cabbage makes a tasty and substantial stew.
The preparation and curing of botillo occurs over a period of at least five days and consists of four phases:
Selection and butchering of the raw material.
Seasoning and stuffing proceeding to the mixing and knead of the gut. Afterwards the cecum is stuffed as before, in its place, were cured and seasoned to achieve the color and the ideal preserving of the tripe.
Smoking, with smoke from natural oak or holm oak (encina) wood.
Dried over two days in drying rooms prepared to ensure that the moisture is finally eliminated and that the product achieves a superior consistency.
